dichlorodimethylsilane or 1,3-dichlorotetramethyldisiloxane with bis(trimethylsilyl) ester of terephthalic acid (1:1 molar ratio, 20°C, 72–144 h) gave 69–97% yields of previously unknown 27- and 22-membered cyclic organosilicon esters of terephthalic acid, respectively. The molecular structures of 22-membered ester 4,4,6,6,12,12,14,14-octamethyl-3,5,7,11,13,15-hexaoxa-4,6,12,14-tetrasila-1,9(1,4)-dibenzacyclohexadecaphane-2
二氯二甲基硅烷或1,3-二氯四甲基二硅氧烷与对苯二甲酸双(三甲基硅烷基)酯的反应(1:1摩尔比,20°C,72–144 h)得到69–97%的先前未知的27和22元成员对苯二甲酸的环状有机硅酸酯。22元酯4,4,6,6,12,12,14,14-八甲基-3,5,7,11,13,15-六氧杂环丁4,6,12,14-四氟-的分子结构通过X射线结构分析研究了对苯二甲酸的1,9(1,4)-二苯甲环己基-2,8,10,16-丁酮和三甲基甲硅烷基酯。
