Treatment of N-heterocyclic silylene Si[N(tBu)CH]_2 and [(η~3-C_3H_5)PdCl]_2 in toluene led to the formation of mononuclear complex (η~3-C_3H_5)Pd{Si[N(tBu)CH]_2}Cl, the silicon analogue to N-heterocyclic carbene complex (η~3-C_3H_5)Pd{C[N(tBu)CH]_2}Cl.

The isomerization of singlet silacyclopropene has been studied by using MP2 method of quantum chemistry with 6 - 31G(d) basis set.

A variety of silacyclohexane,silacyclohexene and silacyclohexadiene derivatives are readily accessible by these transformations.

Due to the ring strain and Lewis acid character, silacyclobutanes and silacyclobutenes can undergo ring expansion reactions to afford five-and six-membered silacycles, or ring opening to give organosilicon molecules and materials as well as fulfill organic transformations under very mild conditions.

Siloles and their fantastic characteristics have attracted much attentions of an increasing number of chemists.
