The reaction of aldehydes and ketones with Appel reagents132 (PPh3-CC14 or -CBr4) has been used as a convenient method for achieving one-carbon homologations. The resulting 1,l- dihalogenomethylene derivatives have found application in the synthesis of acetylenes,* allenes,3 1,3-diynes, and a$- unsaturated mono- and di-carboxylic acids.4 The high versa- tility that vinyl iodides display in organic synthesis5 and photochemistry6 led to us to investigate, as part of a research ...
