A series of seven [IrArNC(NR2)NAr}(cod)] complexes (1a–1g; where R = Me or Et; Ar = Ph, 4-MeC6H4, 4-MeOC6H4, 2,6-Me2C6H3, or 2,6-iPr2C6H3; and cod = 1,5-cyclooctadiene) were synthesized by two different methods from the neutral guanidines, ArN═C(NR2)NHAr, using either MeLi and [Ir(cod)}2(μ-Cl)2] or [Ir(cod)}2(μ-OMe)2]. Reaction of 1a–1g with CO produced the corresponding [IrArNC(NR2)NAr}(CO)2]
一系列的7的[Ir ArNC(NR 2)NAR}(COD)]络合物(1A - 1克;其中R = Me或Et; Ar为pH值,4-MEC 6 ħ 4,4-MeOC 6 H ^ 4,2用两种不同的方法从中性胍ArN═C(NR 2)合成1,6-Me 2 C 6 H 3或2,6- i Pr 2 C 6 H 3和cod = 1,5-环辛二烯)。 NHAr,使用MeLi和[Ir(cod)} 2(μ- Cl)2 ]或[Ir(cod)} 2(μ- OMe)2 ]。1a - 1g与CO反应生成相应的[Ir ArNC(NR 2)NAr}(CO)2 ]配合物(2a - 2g),通过NMR以及溶液和固态红外光谱进行表征。络合物1b(R = Et,Ar = Ph),1d(R = Et,Ar = 4-MeC 6 H 4),1f(R = Me,Ar = 2,6-Me 2 C 6 H 3)和2b(R =的Et中,Ar
