various organolithium reagents to form porphyrins with exocyclic double bonds. The reaction involved conversion with LiR to the respective alcohol. Subsequence dehydratization of the alcohols yielded olefinic systems in which the double bond formed was located in the meso substituent neighboring the β position, i.e., the result of a 1,5-hydride shift. Depending on the organolithium reagent used various olefinic
