Using 2,6- and 2,4,6-alkyl-substituted sterically hindered primary amines, N-bonded silicon dichlorides RN(SiMe3)(Si(Me)Cl2) (R = 2,6-Me2C6H3 (1a), R = 2,6-i-Pr-C6H3 (1b) and R = 2,4,6-Me3C6H2 (1c) have been prepared. Controlled hydrolysis of these dichlorides afforded the N-bonded silanediols RN(SiMe3)(Si(Me)(OH)2) (R = 2,6-Me2C6H3 (2a), R = 2,6-i-Pr-C6H3 (2b), and R = 2,4,6-Me3C6H2 (2c). The X-ray crystal structure of 2c has been carried out. The structure of the diol consists of cyclic hydrogen-bonded dimers linked by further intermolecular hydrogen bonding into a polymeric ribbonlike arrangement.
