Cyclization of 1,2-disilacyclohexa-3,5-dienes initiated by electron transfer reactions with TCNE
Thermal reaction of 1,2-disilacyclohexa-3,5-dienes with tetracyanoethylene (TCNE) gave 8-amino-6,6,11,11-tetramethyl-2,3,4,,5-tetraphenyl-7-aza-6,11-disilatric yclo[5,3,0,1(2,5)]undeca-3,8,10(1)-triene-9,10-dicarbonitrile through a charge-transfer complex.
