中文摘要 | 將化合物[Et N][Mo(CO) (PPh )] 與二硫化碳作用可得到錯合物[Et N] [Mo(CO) (PPh CS )] ,其中錯合物3亦可經由配位基[Et N] [(PPh CS )] 與錯化物Mo(CO) (CH CN)作用而獲得。於錯合物3中,二苯基磷硫代甲酸根配位基,PPh CS ,是以磷原子與金屬鍵結。錯合物3與不同的鹵烷類作用可得到中性的錯合物Mo(CO) [(PPh CS R)](R=C H ,C H OH,C H ,4-6)。醯化作用中,錯化物3與1-氯奈C H C(O)C1作用可得到低產率的錯化物Mo(CO) (PPh CS COC H )] 。烷化與醯化作用皆發生於錯化物的硫原子上。錯化物3與二碘甲烷作用,可得到一個雙金屬錯合物[Mo(CO) (PPh CS )] (��-CH2) ,其中的兩個金屬是以兩個磷的雙芽配位基為架橋而連結。錯化物3的去羰基反應可於乙睛溶劑中進行,獲得一個離子性錯合物[Et N] [Mo(CO) (PPh CS )] 。錯合物9中的二苯基磷硫代甲酸根配位基,PPh CS ,是以磷及一個硫原子與金屬鍵結。所有錯合物皆經由光譜學方法鑑定而知。 |
英文摘要 | Treatment of [Et N][Mo(CO) (PPh )] with CS afforded [Et N] [Mo(CO) (PPh CS )] which was also synthesized from the reaction of Mo(CO) (CH CN) with [Et N] [(PPh CS )] . In complex 3, the diphenylhosphinodithioformato ligand, PPh CS , coordinated to the molybdenum through the phosphorus atom. The reactions of 3 with various alkyl halides yielded the neutral complexes Mo(CO) [(PPh CS R)](R=C H ,C H OH,C H ,4-6). Acylation of 3 with 1-Naphthoy1 chloride [C H C(O)C1] gave complex Mo(CO) [PPh (CS COC H )] with low yield. Alkylation and acylation reactions occurred at the sulfur atom. Complex 3 reacted with CH I to give the dinuclear complex [Mo(CO) (PPh CS )] (��-CH2) in which the two metal atoms are bridged by the bidentate phosphorus ligand. Decarbonylation of 3 in CH CN produced an anionic product which was identified as [Et N] [Mo(CO) (PPh CS )] . The PPh CS ligand of 9 bound to the metal center through both the phosphorus and one of the sulfur atoms. All of the complexes are identified by spectroscopic methods. |
