Abstract
에탄올 용매 중에서, 착물 [(η5-C5Me5)RuCl2]2 (1)에 대하여 과량의 포스핀을 반응시켜 비스(포스핀)루테늄 유도체(η5-C5Me5)RuCl(PR3=PMe3, PMe2Ph, PEt3, PMePh2, 1/2DPPE, 1/2DPPB) (2a∼2f)를 합성하였다. 이 유도체들은 에탄올 용매 중에서 NaBH4와 반응하여 상응하는 황색의 착수소화물 (η5-C5Me5)Ru(PR3)2H (PR3=PMe3, PEt3, PMePh2, 1/2 DPPE, 1/2DPPB) (3a∼3e)을 생성한다. 착염화물 (2a∼2f)와 착수소화물 (3a∼3e)는 모두 결정으로 얻어졌으며, IR, 1H-NMR 그리고 원소분석으로 동정되었다.

Bis(phosphine)ruthenium derivatives (η5-C5Me5)RuCl(PR3=PMe3, PMe2Ph, PEt3, PMePh2, 1/2DPPE, 1/2DPPB) (2a∼2f) have been synthesized by the reaction of [(η5-C5Me5)RuCl2]2 (1) with excessive phosphine in ethanol. The reaction of complexes (η5-C5Me5)Ru(PR3)2Cl with NaBH4 in ethanol gave the corresponding hydride complexes (η5-C5Me5)Ru(PR3)2H (PR3=PMe3, PEt3, PMePh2, 1/2 DPPE, 1/2DPPB) (3a∼3e). Chloride complexes (2a∼2f) and hydride complexes (3a∼3e) were isolated as crystals, which were characterized by IR, 1H-NMR, and elemental analysis.
