The reactions of ZnBr(CF3)*2CH3CN with 1-morpholinocyclo-pentene and -hexene have been investigated and found to yield mixtures of two isomers of 1-morpholino-1-cyanomethyl-2-difluoromethyl-cyclopentane and -hexane, respectively.The interaction with methylene bases of nitrogen heterocycles leads to the formation of trimethinecyanine dyes.This reaction sequence includes the formation of two carbon-carbon bonds in a one-pot operation.The mechanism of the reaction is discussed. - Keywords: Carbenoid reactions; Trifluoromethylelement compounds; Trifluoromethylzinc bromide; Enamines; Methylene bases; NMR spectroscopy; Mass spectrometry; UV-vis spectroscopy
