Abstract

Bis(phosphine)ruthenium derivatives $({\eta}^5-C_5Me_5)RuCl(PR_3)_2(PR_3=PMe_3,\; PMe_2Ph,\;PEt_3,\;PMePh_2$, 1/2DPPE, 1/2DPPB) (2a${\sim}$2f) have been synthesized by the reaction of $[({\eta}^5-C_5Me_5)RuCl_2]_2$ (1) with excessive phosphine in ethanol. The reaction of complexes $({\eta}^5-C_5Me_5)Ru(PR_3)_2Cl\;with\;NaBH_4$ in ethanol gave the corresponding hydride complexes $({\eta}^5-C_5Me_5)Ru(PR_3)_2H (PR_3=PMe_3, PEt_3, PMePh_2$, 1/2 DPPE, 1/2DPPB) (3a${\sim}$3e). Chloride complexes (2a${\sim}$2f) and hydride complexes (3a${\sim}$3e) were isolated as crystals, which were characterized by IR, $^1H-NMR$ , and elemental analysis.

에탄올 용매 중에서, 착물 $[({\eta}^5-C_5Me_5)RuCl_2]_2$ (1)에 대하여 과량의 포스핀을 반응시켜 비스(포스핀)루테늄 유도체$({\eta}^5-C_5Me_5)Ru(PR_3)_2Cl(PR_3=PMe_3,\; PMe_2Ph,\;PEt_3,\;PMePh_2$, 1/2DPPE, 1/2DPPB) (2a${\sim}$2f)를 합성하였다. 이 유도체들은 에탄올 용매 중에서 $NaBH_4$와 반응하여 상응하는 황색의 착수소화물 $({\eta}^5-C_5Me_5)Ru(PR_3)_2Hl(PR_3=PMe_3,\;PEt_3,\;PMePh_2$, 1/2 DPPE, 1/2DPPB) (3a${\sim}$3e)을 생성한다. 착염화물 (2a${\sim}$2f)와 착수소화물 (3a∼3e)는 모두 결정으로 얻어졌으며, IR, $^1H-NMR$ 그리고 원소분석으로 동정되었다.
