K. Ebata et al., INTRAMOLECULAR OLIGOMERIZATION OF DISILALKYLENE (-ME(2)SI(CH2)(N)SIME(2)-) BRIDGED CYCLIC TRIACETYLENES, Chemistry Letters, (12), 1996, pp. 1053-1054
Disilalkylene bridged cyclic triacetylenes are prepared and subjected
to the transition metal complex mediated reactions. In particular, the
reaction with (methylcyclopentadienyl)tricarbonyl-manganese gave a va
riety of pi-electron systems such as fulvene, dimethylenecyclobutene,
and biallene. Structures and reactions of these pi-electron systems ar
e described.
