Abstract

{Bis(mu-t-butylacetato)bis(norbornadiene)dirhodium(I) 1 is prepared by a reaction between pivaloyl camphor and (norbornadiene)rhodium(I) chloride dimer. A molecular rearrangement takes place in which the pivaloyl groups of the pivaloyl camphor starting material are incorporated into the end product as bridging t-butylcarboxylate ligands. A variable temperature H-1 NMR study and corresponding dynamic computer fit of the NMR data, and crystal structure are reported for the structurally nonrigid dimer. Crystals of 1 are triclinic
