The reactive intermediate generated by the addition of <em>tert</em>-butyl and 1,1,3,3-tetramethyl butyl isocyanide to dialkyl acetylenedicarboxylate was trapped by 7-hydroxycoumarin to produce highly functionalized 4<em>H</em>-chromenes in fairly good yields. When the reaction is performed with cyclohexyl isocyanide, 1-azabuta-1,3-dienes were obtained.

One Step

A palladium-catalyzed three-component intermolecular aryl­etherification reaction of ferrocene-substituted allenes, aryl iodides and phenols or alcohols is reported. In this three-component reaction, two new C–C and C–O bonds are formed in one step with high regio- and stereoselectivity. The high selectivity obtained in this reaction can be attributed to the steric effect of the bulky ferrocene group.
