Easily accessible arylgermanium trichlorides were found to undergo palladium-catalyzed cross-coupling reactions with aryl bromides and iodides in good yields. The reaction is performed in an aqueous medium with sodium hydroxide as an activator. Some

This is a historical note of our early works, but not a comprehensive story. Starting from free radical allylation of organic halide with allyltributyltin, we found palladium-catalyzed cross-coupling reactions of organic halides with organotin compou

Reagents containing carbon–tin–halogen inter-element linkages were effective for palladium-catalyzed carbostannylation. In situ generated allyltin trichlorides add to carbon–carbon double bonds of bicyclo[2.2.1]hept-2-ene (norbornene) and bicyc

A racemic 5,12-DiHETE-8,9-cyclopentadiene Diels-Alder adduct was prepared by palladium-catalyzed ternary coupling between vinylic halide, a vinylic tin compound, and norbonadiene in good yields. Both the halide and tin chain were synthesized in excel

Allyl bromide adds to a terminal acetylene under the palladium complex to give 1-bromo-1,4-pentadiene which can further react with organotin compounds without further addition of palladium complex to give 1-substituted 1,4-pentadiene. These two react
