bis(trimethylsilyl) ester of ortho-phthalic acid (1:1, 20°C, 168–264 h) in hexane lead to the formation of previously unknown 14-membered cyclic organosilicon esters of ortho-phthalic acids (silacyclophanones) in 36–85% yields. Molecular structures of 14-membered cyclic ethers 4,10-dimethyl-4,10-diphenyl-3,5,9,11-tetraoxo-4,10-disyla-1,7(1,2)-dibenzacyclododecaphane-2,6,8,12-tetraone, 4,4,10,10-tetramethyl-3
在没有溶剂的情况下,二氯二甲基硅烷与2,3,4,5-四氟邻苯二甲酸双(三甲基硅烷基)醚的反应(1:1,20°C,24 h),二氯(氯甲基)甲基硅烷和二氯(甲基)苯基硅烷与双(三甲基硅烷基)的反应)邻苯二甲酸的邻苯二甲酸酯(1:1,20°C,168–264 h)在己烷中的形成导致以前未知的邻苯二甲酸的14元环状有机硅酸酯(硅环环酮)的形成率为36–85% 。14元环醚4,10-二甲基-4,10-二苯基-3,5,9,11-四氧代-4,10-二甲苯基1,7(1,2)-二苯甲环十二碳六烯2,6的分子结构,8,12-tetraone,4,4,10,10-tetramethyl-3,5,9,11-tetraoxo-4,10-disila-1,7(1,2)-di-(tetrafluorobenza)cyclododecaphane-2 ,6,8,12-丁酮,以及2,3,4,5-四氟邻苯二甲酸的双(三甲基
