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