摘要：
(Z)-(2-Dialkylamino)carbenechromium and -tungsten complexes 3a,b,d,4a and 5c, which are readily available by Michael addition of secondary amines to alkynylcarbene complexes la,b,d and 2c rearrange to aminomethylene complexes 7a,b,d, 8a and 9c, when heated to 50-55-degrees-C. 3a yielded the chelated tetracarbonyl complex 6a at 65-degrees-C.
