isocyanates/isothiocyanates with primary and secondary phosphines without solvent at room temperature afforded phosphinecarboxamide/phosphinecarbothioamide, respectively, in excellent yields. Furthermore, palladium complex Pd(COD)Cl2 was allowed to react with Ph2PC(O)NHPh (1a) to afford [PdPh2PC(O)NHPh-κP}2Cl2] (3). On the other hand, the reaction of Pd(COD)Cl2 with 1 eq. of Ph2PC(S)NHPh (2a) afforded [PdCl2Ph2PC(S)NHPh-κP
异氰酸酯/异
硫氰酸酯与伯膦和仲膦在室温下无溶剂反应,分别以优异的收率得到膦甲酰胺/膦甲
硫酰胺。此外,使
钯络合物Pd(COD)Cl 2与Ph 2 PC(O)NHPh ( 1a ) 反应得到[PdPh 2 PC(O)NHPh-κ P } 2 Cl 2 ] ( 3 )。另一方面,Pd(COD)Cl 2与 1 eq 的反应。Ph 2 PC(S)NHPh ( 2a ) 得到 [PdCl 2 Ph 2 PC(S)NHPh-κ P,S }] ( 4)。在1:2摩尔比的情况下,形成[PdClPh 2 PC(S)NHPh-κ P,S }Ph 2 PC(S)NHPh-κ P }]Cl ( 5 )。使用多元素核磁共振测量和元素分析对新获得的化合物进行了全面表征。此外,Ph 2 PC(O)NH(CH 2 ) 2 Cl ( 1j )、Ph 2 PC(S)NHPh(4-Cl) ( 2c ) 和3 – 5的分子结构采用单晶测定X射线衍射。
