Phosphine oxide of the formula selected from the group consisting of ##STR1## wherein X is H, alkylthio of 1-4 carbon atoms, or ##STR2## Y is H, alkyl of 1-4 carbon atoms, Cl, Br, or ##STR3## Z is H, alkyl of 1-4 carbon atoms, or ##STR4## at least one of X, Y, and Z in the formula in which all three symbols appear is ##STR5## Q is H or Br; each of A and A' is selected independently from H and alkyl of 1-4 carbon atoms, or A and A' taken jointly is CH.dbd.CH--CH.dbd.CH; each of D and D' is selected independently from H and CN, or D and D' taken jointly is CH.dbd.CH--CH.dbd.CH; and each R is selected independently from alkyl of 1-4 carbon atoms, cycloalkyl of 5-6 carbon atoms, benzyl, phenyl, tolyl, and chlorophenyl.
选择公式为 ##STR1## 的膦氧化物,其中X为H、1-4个碳原子的烷基硫或 ##STR2##,Y为H、1-4个碳原子的烷基、Cl、Br或 ##STR3##,Z为H、1-4个碳原子的烷基或 ##STR4##,在所有三个符号出现的公式中,至少有一个X、Y和Z为 ##STR5##,Q为H或Br;每个A和A'独立选择自H和1-4个碳原子的烷基,或A和A'共同为CH.dbd.CH--CH.dbd.CH;每个D和D'独立选择自H和CN,或D和D'共同为CH.dbd.CH--CH.dbd.CH;每个R独立选择自1-4个碳原子的烷基、5-6个碳原子的环烷基、苯甲基、苯基、甲苯基和氯苯基。
