Isocyanides synthesis

Phase transfer catalysis has been applied to the Hofmann isocyanide synthesis, where dichlorocarbene is generated in the presence of a primary amine yields of 40—60% were reported. The synthesis of toIuene-/ -sul-phonylmethyl isocyanide and some alkylated analogues has been described. Isocyanides react with alcohols in thepresence of thalIium(iii)or mercury (u) nitrate to give carbamates the latter salt, while giving lower yields, is more flexible than the former, which is restricted to the use of methanol. ...

A new isocyanide synthesis involves simply heating a monosubstituted aliphatic or aromatic formamlde (readily prepared at 0 from the amine and phenylformate ) in CHCI3 or CH2CI2 with triphenylphosphlne, CCI4 and Et3N. ... [Pg.275]
