含μ_3-S和二胺基卡宾的三核铁羰基簇合物的合成和表征

Synthesis and characterization of trinuclear iron carbonyl clusters containing μ_3-S and diaminocarbene

用 Fe3 ( CO) 12 与 3种硫脲衍生物 Ph NHC( S) NHR( R =H;R =Ph;R =CH2 Ph)在苯 /二氯甲烷 ( 1∶ 1 )混合溶剂及氩气保护下反应 ,合成了 3个新簇合物。经元素分析、MS、IR及 1HNMR谱表征 ,确认新合成的簇合物为含 μ3 -S和二胺基卡宾的三核铁羰基簇合物 Fe3 ( CO) 8( μ3 -S) [C( NHPh) ( NHR) ]

Three trinuclear iron carbonyl clusters containing μ 3 S and diaminocarbene were synthesized from Fe 3 (CO) 12 and thiourea derivatives PhNHC(S)NHR(R Ⅰ=H;R Ⅱ=Ph;R Ⅲ=CH 2Ph) in the benzene/methylene chloride (1∶1) under argon protection.The clusters were characterized by elemental analysis,MS,IR(CO)and 1HNMR spectra.
