Abstract
Products of the reaction of t-butylcyanoketene (TBCK, Moore's ketene) with 4-nitro-, 4-methoxy-, 4-fluoro- and 4-chlorostyrene are presented . Based on the analysis of reaction products we propose a stepwise rea ction mode for the cases of 4-methoxy, 4-fluoro- and 4-chlorostyrene; 4-nitrostyrene reacted in a (2) pi(s) + (2) pi(a) concerted mode.
