Reaktion von trans-1-Arylbutadienen und 1,1-Diarylbutadienen mit Tetracyanethylen (TCNE) und 2,2-Bis(trifluormethyl)ethylen-1,1-dicarbonitril (BTF): Kinetische Studie

Kinetic data (substituent effects, solvent effects, activation parameter) are reported for the reactions of trans-1-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.

Reaktion von trans-1-Arylbutadienen und 1,1-Diarylbutadienen mit Tetracyanethylen (TCNE) und 2,2-Bis(trifluormethyl)ethylen-1,1-dicarbonitril (BTF) : Praeparative Studie.

Trans-1-Arylbutadienes 5 yield normal DIELS-ALDER-adducts 9 and 10 with TCNE 7 and BTF 8.On the other hand 1,1-diarylbutadienes 6 reacting with the same dienophiles give 1:1-adducts 12/13 and/or 14, respectively substitution products 11.At higher temperat
