S-Triphenyl and trialkylgermyl esters of dialkyl dithio- and tetrathio
phosphoric acids, and 4-methoxyphenyldithio- and trithiophosphonic aci
ds were easily obtained in the reactions of tetraphosphorus decasulfid
e and Lawesson's reagent with triphenyl and trialkyl(alkoxy)germanes a
nd (alkylthio)germanes.
