It has been investigated catalytik addition reaction of threealkyl(apil.chlor)silanes to 2-metoxycarbonylbicyclo[2.2.1]hept-5-ene in the presence of platinohydrochloric acid. It has been established that independing of nature and structure of substituents threealkyl(apil. chlor)silanes added to the -HC=CH- double bond with forming silanecontaining bicyclo ether. It was studied properties saturated and unsaturated silanecontaining algohols and their chemical proporties.
