1,1-Disilyl alcohols like 6 give the silyl ethers like 9 on treatment with base and alkyl halides, in a reaction which may be formulated as the alkylation of the Brook-rearranged carbanion 8. The products can be oxidised to give ketones like 10, showing that this Brook-rearranging system supplies a controlled d1 synthon of the acyl anion class. The alcohols can be prepared from the acid chloride 12
1,1-二甲硅烷醇(如 6)在用碱和卤代烷处理后得到甲硅烷基醚(如 9),反应可表述为布鲁克重排碳负离子 8 的烷基化反应。产物可被氧化得到酮(如 10) ,表明该布鲁克重排系统提供了酰基阴离子类的受控 d1 合成子。醇可以由酰氯12和二甲基(苯基)甲硅烷基锂制备,但中间体阴离子21不需要后处理;它可以直接用于烷基化步骤。
