Synthesis of the Novel Ring Systems 1,2,3,4-Oxazadisiletidine and 1,3,4,2,5-Dioxazadisilolidine

摘要

The novel organosilicon rings 2 and 3 were synthesized from the reaction of tetramesityldisilene, 1, with nitrosobenzene and nitrobenzene, respectively. The silicon-silicon coupling constants for the adducts 2 and 3 were determined utilizing the inept-inadequate pulse sequence as modified for Silicon 29 Nuclear Magnetic Resonance. The values obtained support the proposed cyclic structures. Reprints. (aw)
