a range of compounds of the type (Me3Si)3SiSiR2X (R Me, X H; R Ph, X Cl etc.). These compounds can be converted into other derivatives by simple substitution reactions at the SiX centre. Symmetrical pentasilanes (XMe2Si)4Si (X Cl, F, and OAc) have been prepared from (Me3Si)4Si. The reactivities of these species have been compared with those of analogous carbon-centred compounds eg. (Me3Si)3CSiR2X

Halosilylenoids, stable at room temperature (Tsi)X(2)SiLi (Tsi=C(SiMe(3))(3), X=Br, Cl), were synthesized from the reaction of TsiSiX(3) with lithium naphthalenide. Bromosilylenoid reacted with tBuOH and MeI both at -78 degrees C and at room temperature to give (Tsi)HSiBr(2) and (Tsi)MeSiBr(2), respectively, in high yields; this clearly shows its nucleophilicity. In the reaction of bromosilylenoid
