Usage

General Description

Dicyclohexyldimethyltin is a chemical compound that belongs to the organotin group. It is widely used as a heat stabilizer in the production of PVC (polyvinyl chloride) to prevent thermal degradation and enhance the material's fire resistance. It is also employed as a catalyst in the synthesis of organic compounds, such as the production of silicone rubber and as a reactive intermediate in organic chemistry. However, dicyclohexyldimethyltin poses potential health hazards as it is considered to be toxic to aquatic life and can cause skin and eye irritation in humans. It is important to handle this chemical with caution and follow safety guidelines to minimize associated risks.

Surface organometallic chemistry on metals: Controlled hydrogenolysis of Me4Sn, Me3SnR, Me2SnR2, MeSnBu 3 and SnBu4 (R = methyl, n-butyl, tert-butyl, neopentyl, cyclohexyl) onto metallic rhodium supported on silica

The controlled hydrogenolysis of MexSnR4-x (0 ≤ x ≤ 4; R = methyl, n-butyl, tert-butyl, neopentyl, cyclohexyl) onto Rh/SiO 2 is followed by quantitative and qualitative analysis of evolved gases. Only MeH and RH are detected in the evolved gases. There is hydrogenolysis of the Sn-C bonds without any C-C bond hydrogenolysis, leading to formation of grafted organometallic fragments. Using various organotin compounds, MexSnR4-x, it has been possible to determine the regioselectivity of the hydrogenolysis of the Sn-C bonds. The initial selectivity is inversely proportional to the steric bulk of the alkyl group: tBu xR4-x (symmetry D3h), in which the bulkiest group, e.g., R, is away from the surface could explain these results. This surface five-coordinate tin species could eliminate an alkyl group, generally a methyl group, thus decreasing the steric bulk around the tin, into the equatorial plane of D3h, via a concerted hydrogen transfer-elimination mechanism to give Rh-SnMex-1R4-x. Then, in the successive steps of the hydrogenolysis, the bulkiest group, R, would be eliminated.
