Presented here is a new convenient synthetic protocol to (1-propynyl)arenes. The synthesis methodology through one-pot double elimination procedure was developed based on detailed examination of the reaction condition. Reaction of ethyl phenyl sulfone with aryl aldehyde followed by a one-pot double elimination procedure afforded an array of (1-propynyl)arenes in moderate to good yields. Some products included methoxy group, naphthyl and heterocyclic aromatic moieties, and some were borne with two 1-propynyl groups. It is more important that compounds bearing halogens were also synthesized via this protocol. The virtues of this present protocol are facile available starting materials, convenient operation, and easy separation of desired products.

Key words: (1-propynyl)arene, double elimination reaction, one-pot synthesis, examination of reaction condition
