M. Ichinohe et al., Reaction of cyclotrisilene with phenylacetylene: an unusual product with abicyclo[3.2.0]hepta-3,6-diene skeleton, CHEM COMMUN, (2), 2001, pp. 183-184
Cyclotrisilene, ((Bu2MeSi)-Bu-t)(4)Si-3, was reacted with phenylacetylene t
o produce an unusual 1,2,5-trisilabicyclo[3.2.0]hepta-3,6-diene derivative,
whose structure was determined by NMR spectroscopy and X-ray crystallograp
hy; a mechanism for its formation is proposed.
