methyl 2,5-dienoates fromallyl halides, acetylene, carbon monoxide, and methanol at room temperature and atmospheric pressure, based on the formation in situ of the catalytic nickelcomplexfromnickel chloride, is described. A manganese–iron alloy is used as reducing agent and thiourea is used as ligand for the formation of the complex. A mechanism involving a five-co-ordinated complex is proposed.

products of the reaction of methyl propiolate with cyclohexene and some allyl and cyclohex-2-enyl silanes and stannanes (H-ene and M-ene adducts, and [2+2] and [3+2] cycloadducts) have been determined, and rationlised in terms of the probable reaction mechanism. The allylstannanes show only the M-ene reactions to give a mixture of the E- and Z-adducts, and it has been confirmed that the reaction of allylsilanes
