摘要

Abstract Kinetic data (substituent effects, solvent effects, activation parameter) are reported for the reactions of trans-l-arylbutadienes 1 and 1, 1-diarylbutadienes 3 with TCNE 4 and BTF 5.(2+ 2)-and (4+ 2)-cycloadducts 7 respectively 9 can rearrange or undergo- cycloreversions with quite different reaction rates-depending on the substituent in the aryl- ring.
