| Abstract | The interaction of [RuCl<INF>2</INF>(PPh<INF>3</INF>)<INF>3</INF>] with one equivalent of <I>N</I>,<I>N</I>'-bis[2-(diphenylphosphanyl)benzyl]-1<I>R</I>,2<I>R</I>-cyclohexanediamine [1<I>R</I>,2<I>R</I>-P(NH)(NH)P] in dichloromethane at room temperature gave <I>trans</I>-[RuCl<INF>2</INF>{<I>κ</I><SUP>3</SUP>-1<I>R</I>,2<I>R</I>-P(NH)(NH)P}(PPh<INF>3</INF>)] (<B>1</B>). When heated under reflux in toluene under a nitrogen atmosphere, <B>1</B> was converted into <I>trans</I>-[RuCl<INF>2</INF>{<I>κ</I><SUP>4</SUP>-1<I>R</I>,2<I>R</I>-P(NH)(NH)P}] (<B>2</B>). However, when <B>1</B> was stirred at room temperature in air, it was oxidized to <I>trans</I>-[RuCl<INF>2</INF>{<I>κ</I><SUP>3</SUP>-1<I>R</I>,2<I>R</I>-PN(NH)P}(PPh<INF>3</INF>)] (<B>3</B>). Depending on the reaction conditions, <B>3</B> was converted into <I>trans</I>-[RuCl<INF>2</INF>{<I>κ</I><SUP>3</SUP>-1<I>R</I>,2<I>R</I>-P(NH)(NH)P=O}(PPh<INF>3</INF>)] (<B>4</B>) when heated to 80 °C in toluene in air, to <I>cis</I>-[RuCl<INF>2</INF>{<I>κ</I><SUP>4</SUP>-1<I>R</I>,2<I>R</I>-PN(NH)P}] (<B>5</B>) when stirred at room temperature in acetone in air, or to <I>trans</I>-[RuCl<INF>2</INF>{<I>κ</I><SUP>4</SUP>-1<I>R</I>,2<I>R</I>-PN(NH)P}] (<B>6</B>) when heated under reflux in acetone under a nitrogen atmosphere. When heated under reflux in toluene under a nitrogen atmosphere, <B>5</B> isomerized to <B>6</B> quantitatively. When heated under reflux in mesitylene under a nitrogen atmosphere, <B>6</B> was slowly reduced to <B>2</B>. The solid state structures of <B>3</B> and <B>5</B> were ascertained by X-ray crystallography. Catalytic studies showed that <B>1</B> could catalyze the oxidation of alkanes and alkenes with molecular oxygen. |
