The reaction of dialkyl aroylphosphonates 1 with trialkyl phosphites leads to the formation of novel quasiphosphonium ylides 4 which in some cases thermally rearrange to the bisphosphonates 5. 2-Substituted dialkyl aroylphosphonates may also undergo intra

Reaction of trialkyl phosphites with dialkyl aroylphosphonates leads to the formation of anionic intermediates which, in the absence of electrophiles, undergo cleavage at temperatures above about 80 deg C to give carbene intermediates; these undergo intramolecular carbene insertion reactions or are trapped by trialkyl phosphites to give novel ylides.
