an efficient catalyst for the acylativecleavage of C–O bond of ethers with acyl chlorides. When acyclic ethers were allowed to react with acyl chlorides in the presence of a catalytic amount of ReBr(CO)5, acylativecleavage of C–O bond of acyclic ethers smoothly proceeded to give the corresponding esters in moderate to good yields. Similarly, cyclicethers were acylative cleaved by acyl chlorides to
发现rh络合物是醚与酰氯的C-O键的酰基化裂解的有效催化剂。当在催化量的ReBr(CO)5存在下使无环醚与酰氯反应时,无环醚的C-O键的酰基裂顺利进行,从而以中等至良好的收率得到了相应的酯。类似地,使用Re 2 O 7催化剂将环醚酰基氯酰化裂解,得到高产率的相应的氯取代的酯。
