title: Remarkable rate acceleration of Pd(0)-catalyzed hydrogermylation of alkynes and dienes in water.
abstract: [reaction: see text] Without the use of hydrophilic cosolvents or phase transfer catalysts, Pd(0)-catalyzed hydrogermylation of alkynes in water provides dienylgermanes efficiently with high stereo- and regioselectivity. The reaction in water proceeds much faster than the reaction under neat conditions. By using an aqueous system, hydrogermylation can be conducted at a low catalyst loading.
