The present invention provides a method of making a metal complex. The method comprises the steps of: (a) acylating a dipyrromethane or a 1-monoacyldipyrromethane to form a mixed reaction product comprising a 1,9-diacyidipyrromethane; (b) combining the reaction product with a compound of the formula R

in the mixed reaction product, wherein D is a 1,9-diacyldipyrromethane; and then (c) separating the metal complex from the mixed reaction product. The method may be utilized for the convenient synthesis and separation of 1,9-diacyldipyrromethanes. Metal complex intermediates useful in such methods are also described.
本发明提供了一种制备金属配合物的方法。该方法包括以下步骤:(a) 酰化二吡咯甲烷或1-单酰基二吡咯甲烷,形成包含1,9-二酰基二吡咯甲烷的混合反应产物;(b) 在碱的存在下,将反应产物与化合物R2MX2(其中R为烷基或芳基,M为Sn、Si、Ge或Pb(优选Sn),X为卤、OAc、acac或OTf)结合,形成包含公式DMR2的金属配合物的产物,在混合反应产物中,其中D为1,9-二酰基二吡咯甲烷;然后(c) 将金属配合物与混合反应产物分离。该方法可用于方便合成和分离1,9-二酰基二吡咯甲烷。还描述了在这些方法中有用的金属配合物中间体。
