  摘要：

  Consecutive synthesis methodologies for the preparation of carbosilanes (Ph)(Me)Si((CH2)(3)B(OH)(2))(2) (2), Si (C6H4-4-SiMe2((CH2)(3)B(OH)(2)))(4) (5), (Ph)(Me)Si((CH2)(3)OH)(2) (3), and Si(C6H4-4-SiMe3-n((CH2)(3)OH)(n))(4) (6a, n = 1; 6b, n = 2; 6c, n = 3) are reported. Boronic acids 2 and 5 are accessible by treatment of (Ph)(Me) Si(CH2CH=CH2)(2) (1) or Si(C6H4-4-SiMe2(CH2CH=CH2))(4) (4a) with HBBr2 center dot SMe2 followed by addition of water, while 3 and 6 are available by the hydroboration of 1 or Si(C6H4-4-SiMe3-n(CH2CH=CH2)(n))(4) (4a, n = 1; 4b, n = 2; 4c, n = 3) with H3B center dot SMe2 and subsequent oxidation with H2O2.The single molecular structure of 6a in the solid state is reported. Representative is that 6a crystallized in the chiral non-centrosymmetric space group P2(1)2(1)2(1) forming 2D layers due to intermolecular hydrogen bond formation of the HO functionalities along the crystallographic a and c axes.

  Si[C6H4–4-SiMe2(CH2CH=CH2)]4 (7b) and ClSi[C6H4–4-SiC6H4–4-SiMe2(CH2CH=CH2)}3]3 (10a) in the solid state are reported. The crystal structures of both dendrimers are based on C–H···πCC (πCC = double bond of the CH=CH2 groups) and π–π interactions. The 3D network structure observed for 7b is composed of three crystallographically independent head-to-head stacking columns along the crystallographic b axis
