HOCH(Me)(CH2)4SiMe3 − nHn (4a: n = 1, 4b: n = 2, 4c: n = 3), which themselves are accessible by the hydrosilylation of MeCOCH2CH2CHCH2 (1) with the chlorosilanes HSiMe3 − nCln (2a: n = 1, 2b: n = 2, 2c: n = 3) and hydrogenation of the latter species with Li[AlH4]. Alcohols 4a–4c can be used as starting materials for the preparation of carbosiloxane dendrimers of the 1st–3rd generation. For the synthesis of the
