Thermal Dissociation of Disilenes into Silylenes

Extremely hindered and stable disilenes (Tbt(Mes)Si=Si(Mes)Tbt phenyl, Mes=2,4,6-trimethylphenyl. (Z)-1: cis-isomer, (E)-1: trans-isomer>) underwent dissociation under very mild conditions (ca. 70 deg C) into a divalent silicon species (Tbt(Mes)Si: (2)), which was trapped by methanol, triethylsilane, 2,3-dimethyl-1,3-butadiene, elemental sulfur, and elemental selenium to afford the corresponding adducts in good yields.Silylene 2 reacted with some carbon-carbon multiple-bond compounds to afford the corresponding cycloadducts, among which the adduct with 3,3,6,6-tetramethylthiacyclohept-4-yne was established by an X-ray diffraction analysis.Silylene 2 also reacted with naphthalene and benzene to give the corresponding adducts, 15 and 17, respectively, the molecular structures of which were confirmed by X-ray crystallographic analyses.The formation of 15 and 17 represents the first example of cycloaddition of silylenes to aromatic compounds.The thermolysis of 15 and 17 regenerated silylene 2, which was trapped with triethylsilane.A kinetic study of the thermal dissociation of 1 gave the activation parameters, which were compared with those for EZ isomerization of previously reported disilenes.

Syntheses and structures of overcrowded silanedichalcogenols and their applications to the syntheses of silanedichalcogenolato complexes

Overcrowded silanedichalcogenols Tbt(Mes)Si(EH)(E′H), such as silanedithiol (E = E′ = S), hydroxysilanethiol (E = O, E′ = S) and hydroxysilaneselenol (E = O, E′ = Se), bearing an efficient combination of steric protection groups, Tbt and Mes (Tbt = 2,4,6-

Cyclic chalcogenides containing group 13-15 elements

Novel cyclic polychalcogenides containing a variety of heavier main group elements of groups 13, 14, and 15 as ring members have been synthesized as stable crystalline compounds by taking advantage of an effective steric protection group, 2,4,6-tris[bis(trimethylsilyl)methyl]-phenyl (denoted as Tbt in this article). The molecular structures of tetrachalcogenametallolanes of group 14 elements, Tbt(R)ME4 (M = Si, Ge, Sn, and Pb; E = S, Se), and some polysulfides containing antimony or boron atom as a ring member were analyzed by X-ray crystallography to elucidate the skeletal features of these novel ring systems. Dechalcogenation reactions of these cyclic polychalcogenides with trivalent phosphorus reagents provide new and useful synthetic methods for the doubly bonded compouds between the corresponding heavier main group element and a chalcogen atom, a novel class of low-coordinate compounds in the main group element chemistry.
