摘要: The synthesis and several reactions of the stable silylene 1 (1,3-di-tert-butyl-2,3-dihydro-1H-1,3,2-diazasilol-2-ylidene) are described. X-ray crystal structures given for two intermediates in 1, diimine 7 its dilithium salt 8, a byproduct, spiro compound 10. reacts with ethanol water by inserting into O−H bond, iodomethane insertion C−I bond. silanol from reaction condenses to disiloxane, 13. From sulfur selenium, cyclic compounds containing Si2E2 rings obtained (E = S or Se). Crystal presented disiloxane 13 selenium cycloadducts, 15 17.
