The Cu2O-catalyzed reaction of α,β-unsaturated isonitrile with activemethylenecompound is described. Vinyl isocyanide (VIC) and propenyl isocyanide (PPIC) were employed as the isocyanide components. In addition, allyl isocyanide (AIC), which has been known to be rearranged readily to PPIC by Cu2O, was also used as a precursor of PPIC. Five types of products were isolated and identified. These products

Chemoselectivity and structural effects in thermal benzannulation reactions employing chromiumcarbenecomplexes and isonitriles are reported. Alkyl, aryl, sterically hindered, electron deficient, and electron rich isonitriles all react efficiently with several chromiumcarbenecomplexes to provide aromatic amine products.
