2002 polyphenylalkyne derivatives polyphenylalkyne derivatives (tolan derivatives) Q 0750 -110The Effects of π-Acceptor and π-Donor Substitution in Cross-Conjugated Enynes.-Two different donor and acceptor substituted cross-conjugated enynes (II) and (V) are prepared. Their electronic effects are found to be quite depending on the constitution of the enyne framework. -(ZHAO, YUMING; CIULEI, SORIN C.; TYKWINSKI, RIK R.; Tetrahedron Lett. 42 (2001) 44, 7721-7723; Dep.
