groups of silicon-containing alkenes is reported. It includes a highly regioselective functionalization of 1,5-hexadiene through hydrosilylation and dehydrogenative silylation with organofunctional silanes and siloxanes. The established conditions enable selective monofunctionalization of 1,5-hexadiene regardless of the organosilicon modifier used as well as the type of functional group bonded to the silicon-based
selective approach for the synthesis of new organofunctional triallyl isocyanurate derivatives, via hydrosilylation reaction with silanes and siloxanes bearing attractive functional groups, is reported. The presence of Pt-Karstedt's complex led to the total conversion of reagents, as well as, the formation of β-regioisomeric products. The new compounds are valuable building blocks for the synthesis of a
The first protocol for the synthesis of unsymmetrical bifunctional 1,1,3,3-tetramethyldisiloxane derivatives via subsequent hydrosilylation of alkenes and alkynes is presented. The methodology described has vast functional group tolerance and is extremely efficient towards the formation of novel disiloxane-based building blocks.
reported. On the basis of a study of platinum- and rhodium complexes in the reactions between TMDSO and selected olefins containing C=C bond, it was possible to choose the most efficient catalyst whose application in the solvent-free system led to selective mono-functionalization of the disiloxane reagent and simultaneous formation of only β-regioisomeric products, bearing in their structure functional

Hydrosilylation of allyl ethyl, allyl butyl, allyl glycidyl, allyl benzyl, and allyl phenyl ethers by 1,1,3,3-tetramethyldisiloxane in the presence of supported sulfur-containing platinum(II) complexes with the general formula [SiO2}O2Si(Me)(CH2)3SR]2PtCl2 (R = Bu, Hex, Bn; SiO2} is silica surface) and side processes have been studied.
