  摘要：

  Starting from 2,2-dichloro-methylcyclosiloxanes [-OSiCl2-(OSiMe2)(n)-] (1a-c) [n: 1, 2, 3] the corresponding 2,2-dihydroxymethylcyclosiloxanes [-OSi(OH)(2)-(OSiMe2)(n)-] (2a-c), the 2,2-dimethoxy-methylcyclosiloxanes [-OSi(OMe)(2)-(OSiMe2)(n)-] (3a-c), the 2,2-difluoro-methylcyclosiloxanes [-OSiF2-(OSiMe2)(n)-] (4a,b) [n: 2, 3], the 2,2-dihydrido-methylcyclosiloxanes [-oSiH(2)-(OSiMe2)(n)-] (5a,b) [n: 2, 3] and two spirosiloxanes [-(OSiMe)(m),-OSi-][-OSi-(OSiMe2)(n)-] (6a,b) [m,n: a: 3, 1; b: 2, 3] have been synthesized and characterized by NMR-, MS and partly by IR spectroscopy. 2a is stable in diluted solution only. 2b forms a crystalline 1:1 adduct with H2O characterized by X-ray analysis as a highly organized tube like structure.
