Pd(OAc)2. Complexes 1 and 2 react with isocyanides R'NC (R’ = C6H4Me2-2,6 (Xy), C6H4I-2 and tBu) to give complexes of the type [PdC,C-C(CO2R) = C(NHR′)}(CHCO2R)}PPh2}Cl(CNR′)], resulting from the insertion of the unsaturated molecule in one of their Pd–C bonds and the hydrogen transfer from the methine CH to the iminobenzoyl nitrogen. These are the first insertion reactions observed in the Pd–C bond
以前报道的络合物[Pd (C,C– CHCO 2 R)2 PPh 2 }(μ-Cl)] 2(R = Me(1),Et(2))的合成已通过与salts盐[Ph 2 P(CH 2 CO 2 R)2 ] Cl与Pd(OAc)2。配合物1和2与
异氰酸酯R'NC(R'= C 6 H 4 Me 2 -2,6(Xy),C 6 H 4 I-2和t Bu)反应,得到[Pd C,C- C(CO 2 R)= C(NHR')}(CHCO 2 R)} PPh 2 } Cl(CNR')],是由于不饱和分子插入其Pd–C键之一氢从次甲基CH转移到亚
氨基苯甲酰氮。这些是在P-ylide配合物的Pd-C键中观察到的第一个插入反应。报告了复合物[Pd C,C- C(CO 2 Me)= C(NHXy)}(CHCO 2 Me)} PPh 2 } Cl(CNXy)]的晶体结构(3)。
