Hydrides of group IVB elements have been prepared in high yield by heterogeneous reduction of the corresponding halo, alkoxy and amino derivatives using lithium aluminium hydride in non-polar solvents under ultrasonic irradiation.
Reactions of heteroarylhydrosilanes with dichlorocarbene under phase-transfer conditions
Lukevics, E.,Sturkovich, R.,Goldberg, Yu.,Gaukhman, A.
, p. 19 - 26 (1988)
The reactions of dimethyl(2-thienyl)-, methyl-, tri(2-thienyl)- and dimethyl(2-furyl)silanes (I-IV, respectively) with dichlorocarbene generated from sodium trichloroacetate under solid-liquid phase-transfer conditions afford the corresponding dichloromethylsilanes in 38-66percent yield.The reactivity of the thienylsilanes decreases with the number of electron-accepting thienyl substituents at the silicon atom.Using the competition reactions, the relative rate constants for the reaction of dichlorocarbene insertion into the Si-H bond of thienyl- and furyl-silanes (I and IV) were measured.The reactivity of these silanes was found to be greater than had been expected taking as a basis the Taft ?* constants for the substituent at the silicon atom.This is apparently due to the existence of a p?-d? interaction between the heterocyclic ?-system and the d-orbitals of silicon.
Regiospecific and stereoselective syntheses of (±)-reserpine and (-)-reserpine
Stork, Gilbert,Tang, Peng Cho,Casey, Michael,Goodman, Burton,Toyota, Masahiro
, p. 16255 - 16262 (2007/10/03)
Full details of three approaches to an entirely regio- and Stereoselective synthesis of the well-known target reserpine are described, culminating in a total synthesis which efficiently meets these requirements.
Cleavage of Si-C and Ge-C bonds in heterylsilanes and -germanes by organolithium reagents
Gevorgyan, Vladimir,Borisova, Larisa,Lukevics, Edmunds
, p. 381 - 387 (2007/10/02)
Organolithium reagents RLi can cleave Si-C and Ge-C bonds in heterylsilanes and -germanes substituting furyl, dihydrofuryl and dihydropyranyl groups for the organolithium residue R.
