    Abstract: Ru(NH)NCR錯合物(R = -C H CH ,-C H ,-C H Cl,-CH CH,-CH ,-CH COOC H )氧化成Ru(Ⅲ)時,配位上之 基發生水解反應.元素分析,吸收光譜,IR光譜均支持水解產物為Ru(NH?)?NHCOR 錯合物,在酸性及鹼性水溶液中,水解反應速率與取代基的關係已被探討.在苯系列取代基R = -C H CH ,-C H ,-C H Cl 對位取代群對水解速率的影響並不明顯,其速率常數在pH= 5,= 0.1M LiClO 分別為1.71×10sec,2.01 ×10sec,及3.79×10sec.而在pH= 8,μ= 0.1MLi- CLO,速率常數則為pH= 5的20倍左右,pH=10則為200倍左右,在同樣條件下(pH= 5),乙系列取代基R = -CH?CH,-CH速率常數為0.37×10sec及1.31×10sec而R = -CH COOC H 則超過stopped- flow的時間尺度.在0.1M HClO?溶液中,測得R = -CHCOOC H 溶液中,測得速率常數為2.61×10sec,較同條件的R= -CH?(≦8×10sec)快30倍以上
