Synthesis of trans-9-(2-Phenylethenyl)anthracene Introduction The purpose of this experiment was to convert carboxyl compounds into alkenes. While this reaction yields both the E and Z isomers‚ it is preferred over other reactions due to the lack of uncertainty of where the double bond is positioned. Also the stability of an ylide determines which isomer is the major product. 1 Experimental: Compounds Benzyltriphenylphosphonium chloride 9-Anthraldehyde 50% Aqueous NaOH DCM Product Formula weight
