โœฆ Synopsis

In the preceding communication (l), we have reported that primary and secondary amines react with isocyanide in the presence of copper compound as the catalyst to produce amidines in almost quantitative yields.

N-R "

In view of the fact that carbon monoxide is isoelectronic with isocyanide (2), the above finding prompted us to explore the possibility of the reaction of amine with carbon monoxide by copper catalyst. R-E\j=C:+--R-NzC: Isocyanide :ij=c: B :ozc: Carbon monoxide Now we have found that copper compounds as well as metallic copper catalyze the reaction of primary and secondary 6125

Recently we have reported that in the presence of cuprous chloride as catalyst isocyanide (I) reacts with p,r-unsaturated alcohol (II) to produce the corresponding formimidate (III)l).
