A Simple Catalytic Route for Alkynylgermanes

We report a new one-pot, iridium(I)-catalyzed direct method for the synthesis of alkynyl-substituted germanium compounds with various functional groups from commercially available reagents. More than 25 compounds were obtained and spectroscopically charac

The enthalpies of formation of triphenyl vinyl germanium, triphenyl phenylethynyl germanium, bis(triphenyl germanium) oxide, and some associated Ge-C bond enthalpies

The three compounds (C6H5)3GeCH=CH2, (C6H5)3GeCC(C6H5), and 2O, have been burnt in an aneroid combustion calorimeter and their vapour pressures measured by an effusion method.The gas-phase enthalpies of formation: ΔfH0sub
