摘要

Reaction of N,N-diallylbenzamide with Na_2Fe(CO)_4 and Me_3SiCl afforded chelated cis-tricarbonyl[(#eta#~2-N-allyl-N-allylamino)(phenyl)carbene]iron(0) directly. The same reaction of N-(3-buten-1-yl)-N-methylbenzamide proceeded with migration of the double bound to the allylic position, giving a mixture of chelated cis-tricarbonyl[(#eta#~2-N-(2-butenyl)-N-methylamino)(phenyl)carbene]iron(0) and nonchelated tetracarbonyl[(N-(2-butenyl)-N-methylamino)(phenyl)carbene]iron(O). N-(3-Buten-2,2-dimethyl-1-yl)-N-methylbenzamide, in which migration of double bond is not possible, gave a mixture of E and Z isomers of nonchelated tetracarbonyl-[(N-(2,2-dimethyl-3-butenyl)-N-methylamino)(phenyl)carbene]iron(O). Thermolysis of the latter furnished 1-methyl-3,3-dimethyl-6-phenyl-1,2,3,4-tetrahydropyridine as the only product.
