The invention relates to novel oligomeric silasesquioxanes having the formula R6Si6O9 (R = alkyl, cycloalkyl (c-C3H5, c-C4H7, c-C5H9, c-C7H13, c-C6H15, c-C9H17, c-C10H19), alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl, heteroaryl) and the structure I and also to a process for preparing oligomeric silasesquioxanes having the formula R6Si6O9 (R = alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl, heteroaryl) and the structure 1 and also to their use for the synthesis of incompletely condensed silasesquioxanes, of catalysts and their starting compounds and also of polymers. |
