Silacyclophanones 2*. Cyclic organosilicon esters of terephthalic acid

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

The reactions of 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-2,8,10,16-tetraone and trimethylsilyl ester of terephthalic acid were studied by X-ray structural analysis.
