A series of (diazoalkane)rhodium(I) compounds of the general composition trans-[RhCl(N2CRR‘)(PiPr3)2] with R = R‘ = Ph, p-C6H4Me, p-C6H4Cl and R = Ph, R‘ = p-C6H4Me, o-C6H4Me, CH3, CH2Ph, CF3 has been prepared from the dimer [RhCl(PiPr3)2]2 (1) and the diazoalkane. This preparative route has also been extended to complexes in which the N2C unit(s) of 1,4-C6H4C(Ph)N2}2, 9-diazofluorene, 9,10-anthraquinone-9-diazide
一般组成的一系列(重氮烷)铑(I)化合物反式-[RhCl(N 2 CRR')(P i Pr 3)2 ],R = R'= Ph,p -C 6 H 4 Me,p -C 6 H 4 Cl和R = Ph,R'= p -C 6 H 4 Me,o -C 6 H 4 Me,CH 3,CH 2 Ph,CF 3由二聚体[RhCl(P i Pr 3)2 ]2(1)和重氮烷。该制备途径也已扩展到其中1,4-C 6 H 4 C(Ph)N 2 } 2的N 2 C单元,9-重氮芴,9,10-蒽醌-9-的配合物。二叠氮化物和3-甲基-1,4-萘醌-1-二叠氮与14电子[RhCl(P i Pr 3)2 ]片段连接。C(CO 2 Et)2 N 2的行为与预期相同,用1处理后即可得到复杂的反式-[RhCl N 2 C(CO 2 Et)2 }(Pi Pr 3)2),CH(CO 2 Et)N 2与相同的原料反应,生成二氮衍生物反式-[RhCl(N
