Several pentaalkylguanidines have been prepared and found to be superior catalysts for the preparation of aryl and aralkyl ethers from carbonates and for the methylation of phenols with dimethylcarbonate. They also act as effective catalysts for esterification of acids with alkyl chloroformates but not for the acetylation of tertiary alcohols with acetic anhydride.
已经制备了几种五烷基胍,并且发现它们是用于由碳酸盐制备芳基和芳烷基醚以及用于苯酚与碳酸二甲酯甲基化的优良催化剂。它们也可作为有效的催化剂,用于酸与烷基氯甲酸酯的酯化反应,而不是叔醇与乙酸酐的乙酰化反应。
