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 α,β-unsaturated acylgermanes in good yields. Conversion of acylgermanes to the corresponding amides is achieved.
