The thermal redistribution of P4S10 with (RS)3PS (R = alkyl or aryl) generates metaphosphorotrithioic esters (RSPS2)2 and relatively smaller amounts of symmetrical [(RS)2P(S)]2S as ‘middle’ and ‘end’ species respectively. Reacting P4S10 with thiols affords similar mixtures. With dithiols HS(CH2)nSH (n= 2 or 3), no ‘middle’ compound was obtained but only ‘end’ and ‘ortho’ derivatives, chiefly [AS2P(S)]2Y
P 4 S 10与(RS)3 PS(R =烷基或芳基)的热重分布产生偏磷酸三硫代酸酯(RSPS 2)2和相对少量的对称[(RS)2 P(S)] 2 S作为“中间” '和'end'物种。P 4 S 10与硫醇反应可得到相似的混合物。使用二硫醇HS(CH 2)n SH(n = 2或3),没有得到“中间”化合物,只有“端”和“邻”衍生物,主要是[AS 2 P(S)] 2 Y(A =亚烷基) ,Y分别为–S–或–SAS–)。
