C6H5CH2, C6H8) react with compound Ia at 130°C to give the corresponding methyl dithioesters. Carboxylic acids RCOOH (R = C6H8-CH2, C6H8) react with compound Ib at 200°C for 15 min to give the corresponding ethyl dithioesters, while low boiling acids (R = CH3, C2H8, n-C3H7) yielded mixtures of the corresponding ethyl dithioester and ethyl carboxylate. Carboxylic acid chlorides RCOCl (R = ClCH2, C2H5
由0,0-二甲基二硫代磷酸Ia和P 4 S 10在160℃下制备2,4-二甲硫基-1,3,2,4-二硫代二膦烷2,4-二硫化物IIa 。2,4-双(4-苯氧基苯基)-1,3,2,4-二硫代二ophophaneane 2,4-二硫,IIc和2,4-双(4-苯基硫代苯基)-1,3,2,4-二硫代二膦烷2在4-60℃下分别由P 4 S 10和二苯醚和二苯硫醚制备1,4-二硫化物IId 。羧酸RCOOH(R = CH 3 C 2 H 5,nC 3 H 7,nC 4 H 9,C 6 H 5 CH 2,C 6 H8)在130℃下与化合物Ia反应,得到相应的甲基二硫酯。羧酸RCOOH(R = C 6 H 8 -CH 2,C 6 H 8)在200°C下与化合物Ib反应15分钟,得到相应的乙基二硫酯,而低沸点酸(R = CH 3,C 2 H在图8中,nC 3 H 7)产生相应的二硫代乙酯和羧酸乙酯的混合物。羧酸氯化物RCOCl(R
