Pd(0)-catalyzed reaction of alkynes with trifurylgermane and CO providing acylgermanes: the example of hydrometalcarbonylation of alkynes.

A direct synthesis of acylmetals from alkynes with group 14 metal hydride and CO is reported. The Pd(0)-catalyzed reaction of alkynes with tri(2-furyl)germane under ambient pressure of CO provides alpha,beta-unsaturated acylgermanes in good yields. Conversion of acylgermanes to the corresponding amides is achieved.
