Abstract

Abstract Reaction of ClCH 2 CH 2 PCl 2 with ethylene oxide gives the phosphonous acid ester ClCH 2 CH 2 P (OCH 2 CH 2 Cl) 2 which on heating to 120 rearranges to the phosphinic acid ester (ClCH 2 CH 2) 2 P (O) OCH 2 CH 2 Cl (3). Chlorination of 3 with PCl 5 in CCl 4-solution yields the phosphinic chloride (ClCH 2 CH 2) P (O) Cl (4), which on treatment with P 2 S 5 at 170 produces the thioderivative,(ClCH 2 CH 2) 2 P (S) Cl,(5). ...
