Carbon-13 and phosphorus-31 n.m.r. spectra have been obtained for a series of phenyl-phosphonothioic di(monoalkylamides), PhP(S)(NHR)2(R = H, Me, Et, Prn, Pri, cyclopropyl, Bun, Bui, Bus, But, neopentyl, cyclopentyl, cyclohexyl, or CH2Ph). Inductive and resonance substituent coefficients have been evaluated using the dual-substituent parameter method from the relative shieldings of the meta- and para-carbon
已获得一系列苯基膦硫基二(单烷基酰胺),PhP(S)(NHR)2(R = H,Me,Et,Pr n,Pr i,Pr i,环丙基,Bu的碳13和磷31 nmr光谱n,Bu i,Bu s,Bu t,新戊基,环戊基,环己基或CH 2 Ph)。电感和共振取代基系数被采用双取代参数法从相对shieldings评估元-和对位-苯环中的碳原子核。还尝试将来自不同nmr测量值的数据与化学行为相关联,并探索上述一组化合物的碳13和磷31 nmr化学位移数据之间的关系。
