Abstract

Oligosilsesquioxanes I [R = (cyclo)alkyl, (cyclo)alkenyl, (cyclo)alkynyl, aryl, heteroaryl] and their metal complexes or precursors are prepd. Adding 100 mL H2O cautiously to a stirred, boiling soln. of 100 g C6H11SiCl3 in 400 mL acetone, stirring at room temp. for 168 h, washing the resulting solids with acetone, drying, and stirring 1 part solid with 5 parts pyridine for 30 min gave 21.0% I (R = C6H11). Prepn. of Ti complexes and of the silsesquioxanes R6Si6O7(OH)4 are exemplified. [on SciFinder (R)]
