synthesis of trans -9-(2-phenylethenyl) anthracene
In synthesis of trans-9-(2-phenylethenyl) anthracene a carbonyl group is converted to a benzylidene group by reaction with the ylide derived from benzyltriphenylphosphorium chloride. Would it have been possible to use the ylide derived from benzyltrimethylphosphonium chloride in this reaction? Answer the same question for the case in which benzyl is replaced by ethyl. What is involved?
