	abstract = {Recently, esters have received much attention as transmetalation partners for cross-coupling reactions. Herein, we report a systematic study of the reactivity of a series of esters and thioesters with [{(dtbpe)Ni}2(μ-η2:η2-C6H6)] (dtbpe=1,2-bis(di-tert-butyl)phosphinoethane), which is a source of (dtbpe)nickel(0). Trifluoromethylthioesters were found to form η2-carbonyl complexes. In contrast, acetylthioesters underwent rapid Cacyl-S bond cleavage followed by decarbonylation to generate methylnickel complexes. This decarbonylation could be pushed backwards by the addition of CO, allowing for regeneration of the thioester. Most of the thioester complexes were found to undergo stoichiometric cross-coupling with phenylboronic acid to yield sulfides. While ethyl trifluoroacetate was also found to form an η2-carbonyl complex, phenyl esters were found to predominantly undergo Caryl-O bond cleavage to yield arylnickel complexes. These could also undergo transmetalation to yield biaryls. Attempts to render the reactions catalytic were hindered by ligand scrambling to yield nickel bis(acetate) complexes, the formation of which was supported by independent syntheses. Finally, 2-naphthyl acetate was also found to undergo clean Caryl-O bond cleavage, and although stoichiometric cross-coupling with phenylboronic acid proceeded with good yield, catalytic turnover has so far proven elusive.},

A new structural model is found which corresponds to a modified version of the copper sulphide overlayer model first proposed by Domange and Oudar. In that model, the topmost layer has 3/7 monolayer each of Cu and S atoms, but the modification involves one S atom per unit mesh moving down to displace a Cu atom from the second metal layer. Relaxations among the topmost Cu atoms result in one S atom being effectively three-fold coordinate while the other two are sixfold coordinate and 12-fold coordinate: the averaged S-Cu bond lengths are indicated to equal 2.19, 2.47 and 2.62 Angstrom respectively. Some discussion is included of factors that may influence this choice of surface structure. (C) 1999 Elsevier Science B.V. All rights reserved.},

This surface has a novel structure in which each phosphorus atom bonds to seven neighbouring Ni atoms, four in the top layer and three in the second layer, at an average distance close to 2.39 Angstrom. Formally this reconstruction involves three neighbouring Ni atoms in a triangular arrangement per unit mesh of the original unreconstructed surface being replaced by three phosphorus atoms. A discussion is included of the structural relaxations that occur in this surface as the demands of Ni-P bonding are balanced against those for Ni-Ni and P-P contributions.

	abstract = {The coastal forests of British Columbia have large accumulations of coarse woody debris, and information on this pool is considered essential in developing sustainable management practices. We characterized coarse woody debris (7-12 and >12 cm diameter) in forest chronosequences of four age classes located on the eastern and western sides of Vancouver Island. For three species (Douglas-fir (Pseudotsuga menziesii (Mirb.) France), western hemlock (Tsuga heterophylla (Raf.) Sarg), western red cedar (Thuja plicata Donn.)) and unidentified samples, increases in decay class (I to V, assigned in the field) were associated with decreasing density, and small increases in concentrations of C, N, and P. Sulfur concentrations (0.6-2.4 g/kg) were higher than those found elsewhere for wood and did not show any significant changes with decay class. C-13 nuclear magnetic resonance spectroscopy with cross polarization and magic-angle spinning (C-13-CPMAS-NMR) was used to analyze organic components in a subset of samples >12 cm. Logs up to decay class III generally showed little change in composition or a slight increase in polysaccharide C. After this, polysaccharide was lost more quickly and logs of decay class V were composed almost entirely of lignin, a pattern consistent with decay by brown-rot fungi. However, two samples of western red cedar decay class III and IV showed accumulation of polysaccharide, the pattern expected from white-rot fungi. The results of the density, chemical and NMR analysis indicate that for management purposes, a system with fewer decay classes would suffice. (C) 1998 Elsevier Science B.V.},

Comparisons are made with the structure recently determined for the corresponding P/Rh(lll) system. In both cases, the atomic density in the reconstructed layer increases to five metal atoms and three chemisorbed atoms for every seven atoms in the regular metal surface. Some details are closely similar between the two systems, but an intriguing difference is also indicated. In S/Pd(lll), four metal atoms in each pentagonal ring appear close to hcp-type three-fold sites, while the other is close to a fee-type three-fold site. This contrasts with the situation for the topmost layer of the P/Rh(lll) system, for which the reversed lateral registry has been reported (i.e. the atoms of each pentagonal ring occupy three-fold sites where four are of the fee type and one of the hcp type).

Bucklings are indicated in the second metal layer of magnitudes 0.01 and 0.06 angstrom for the c(2 x 2) and p(2 x 2) surfaces respectively; for the latter structure the top layer metal atoms are laterally relaxed by around 0.05 angstrom. A surprising feature in the present work concerns the possibility that S is displaced laterally from the symmetrical centre site of 4-fold coordination, by around 0.27 angstrom, toward bridge sites. This shifting of S has a small, but definite, effect on the intensity curves of the higher order fractional beams. At this time, it does not appear as an artefact introduced by uncertainties in the direction of incidence, the second metal layer buckling or the surface Debye temperature.},
