Ruthenafurans [R[graphic omitted]H}ClL2](L = PMe2Ph, R = CHCHOEt, CHCHCMe3, Me or Ph; L = PMe3, R = CHCHOEt or CHCHPh) can be formed reversibly from [Ru(CO)2RClL2] and EtOCCH: the rate-determining forward step involves the formation of the intermediate [Ru(CO)(COR)ClL2], which can be trapped when the reverse reaction occurs in the presence of Me3CNC.
呋喃呋喃[R] [H] ClL 2 ](L = PMe 2 Ph,R = CH CHOEt,CH CHCMe 3,Me或Ph; L = PMe 3,R = CH CHOEt或CH CHPh)可以由以下方法可逆地形成[Ru(CO)2 RClL 2 ]和EtOC CH:决定速率的正向步骤涉及中间体[Ru(CO)(COR)ClL 2 ]的形成,该中间体在存在下列条件下发生逆反应时会被捕获:我3 CNC。
