Transmetalation of Acyclic Tungsten Carbenes to Coinage Metals: Distinct Behavior of Silver toward Carbene Transfer and Hydrolysis
[component]
unpublished
The transmetalation of acyclic monoamino and alkoxo carbenes from tungsten to group 11 metals has been studied for all three metals by analyzing the new metal carbenes formed and also their decomposition products in solution. The ease of transmetalation follows the trend: Au > Cu > Ag and the gold carbenes can be isolated, a copper carbene could be detected but we found no experimental evidence of the formation of any silver carbene. The electrophilic character of copper and gold carbenes is
