Phosphoric Acid Derivatives of Tin. I. Triorganotin(IV) Dithiophosphate Esters

摘要

Twelve triorganotin dithiophosphate esters, R3SnS2P(OR prime)2, where R=C6H5- and R prime=CH3-, C2H5-, n-C3H7-, i-C3H7, N-C4H9-, i-C4H9 and C6H5-; and R=CH3- and R prime=CH3-, C2H5-, n-C3H7- and i-C3H7-; and R-C6H11- and R prime=i-C3H7- were synthesized in high yield by the condensation of the organotin hydroxide with the 0,0 prime-diorganodithiophosphoric acid to release water which was distilled azeotropically, or taken up in an alcohol solvent corresponding to the phosphoric acid ester group, or by the reaction of the triorganotin chlorides with an alkali metal salt of the dithiophosphoric acid.
