✦ Synopsis

We have prepared &ethyl o-phenylenediacrylate, .s substituted pdivinylbenzene, by a Wittig reaction, and have found that its photochemistry differs significantly from that reported for c=divinylbenzenes (1,2) and other susbtituted divinyl arenes (31, and the formally analogous 1,3,5-hexatrienes. A solution of carbethovmethylenetriphenylphosphorane (4) in benzene was added to a solution of phthaladehyde (in benzene) and heated at reflux for 18 hours to give, after purification, a 58% yield of trsns-trsns-o-phenylenediacrylate (I), m.p. (from ether) 77.5-7&' (lit. (5) m.p.
