摘要

Synthe4ses of novel 1,3-diphenyldisiloxanes were investigated.1,1,3,3-Tetrachloro-1,3-diphenyldisiloxane (1) and 1,1,3,3-tetraisocyanato-1,3-diphenyldisiloxane (2) were obtained by vapor-phase hydrolytic condensation of trichloro-(phenyl)silane and triisocyanato9phenyl)silane,respectively.The reactionsof 1 with 2-propanol,t-butyl alcohol,and diethylamine provided 1,1,3,3-tetrakis(diethylamino)-1,3-diphenyldisloxane (6),respectively.1,3-Diisocyanato-1,3-diiso-propoxy-1,30-ciphenyldisiloxane (4) and 1,3-di-t-butoxy-1,3-diisocyanato-1,3-diphenyldisiloxane (5b) were synthesized by the reactons of 2 with 2-propanol and with t-butyl alcohol,respectively.Hydrolysis of 5a or 5b afforded 1,3-di-t-butoxy-1,3-diphenyldisiloxane-1,3-diol (7).1,3-Diphenyldisiloxane-1,1,3,3-tetrol (8) was isolated from the hydrolyis of 1.A single crystal X-ray diffraction of 8 showed that four hydroxy groups are facing each other to form a ladder-type network by the intermolecular hydrogen bondings.
