L. Roelofs andH. Arn, Nature, Lond.219, 513 (1968). Purities were about 90% by GLC.Cis-8-dodecenyl acetate was obtained from Zoecon Corporation as Funemone caps or from Farchan Chemicals;trans-8-dodecenyl acetate was a gift from Zoecon Corporation. Undecylenic alcohol and acetate were commercial grades. The remaining chemicals were kindly supplied by Drs.W. L. Roelofs andA. Hill, Cornell University, Geneva, N. Y., USA.
