by IR spectroscopy and X-ray crystallography. In the IR spectra of 9-11, SO(2) asymmetric stretchingabsorptions (nu(SO2)) were observed at lower wavenumbers as compared to those of phosphorus counterparts 8. The difference in frequency (Deltanu(SO2)) from 8 increased progressively as the pnictogen element being utilized moved down the group 15 column on the periodic table. X-ray crystallographic analyses
三芳基膦1(Ar(3)P; Ar = Ph,4-MeC(6)H(4)),三苯基ar烷(2)和三芳基苯乙烯3(Ar(3)Sb; Ar = 2-MeC(6)H( 4),2-MeOC(6)H(4))与三氟甲磺酰胺(7a)在等摩尔的偶氮二乙基二羧酸二乙酯存在下反应,得到相应的三芳基(磺酰亚胺)吡咯烷烷[Ar(3)M = NSO(2)CF(3) ); 8(M = P),9(M = As),10(M = Sb)]。三芳基二氯化锑5(Ar(3)SbCl(2); Ar = 2-MeC(6)H(4),2-MeOC(6)H(4))和三芳基二氯化铋6(Ar( 3)BiCl(2); Ar = 2-MeC(6)H(4),2-MeOC(6)H(4),2,4,6-Me(3)C(6)H(2))与磺酰胺7(H(2)NSO(2)R; R = CF(3),4-MeC(6)H(4),Me)在2当量的叔丁醇钾存在下产生三芳基(磺酰亚胺)
