Abstract | {Reaction of pyridinium and phosphonium 2-carboxy-1-formyl-2-oxoethylides with oxybis(diphenylborane) yields 5-(2-oxo-1-(pyridinio or phosphonio)ethylidene)-2,2-diphenyl-1,3-dioxa-2-borata-4-cyclopentanones , which represent novel types of boron nitrogen and boron phosphorus betaines, respectively. Crystals of 5-(2-oxo-1-pyridinioethylidene)-2,2-diphenyl-1,3-dioxa-2-borata-4-cyclop entanone, 1a, are monoclinic |
