A novel oxidative cyclisation onto vinyl silanes.
A novel osmium-catalysed oxidative cyclisation of 1,2-diols bearing a pendant vinyl silane affords THFs that contain silicon functionality at the ring junction. When the cyclisation occurs onto a vinyl benzyldimethylsilyl group, the resulting silyl group can act as a masked hydroxyl group and undergo a Fleming-Tamao type oxidation at a later stage to form the corresponding lactol. The scope of ...
متن کاملSelective synthesis of functionalized, tertiary silanes by diastereoselective rearrangement-addition.
[reaction: see text] Treatment of hydroxy-substituted silyl epoxides with Grignard reagents induces a 1,2-carbon shift to reveal alpha-silyl aldehydes, which are trapped by highly diastereoselective addition reactions of the Grignard reagent. The starting epoxides are readily accessible from propargylic alcohols by regio- and diastereoselective hydrosilylation and epoxidation reactions. In addi...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولOxidative addition of SiH4 and GeH4 to Ir(PPh3)2(CO)Cl: structural and spectroscopic evidence for the formation of products derived from cis oxidative addition.
X-ray diffraction studies demonstrate that oxidative addition of SiH(4) to Ir(PPh(3))(2)(CO)Cl yields Ir(PPh(3))(2)(CO)(Cl)(SiH(3))H, which features a cis arrangement of the SiH(3) and H ligands in which H is located trans to CO, rather than trans to Cl as originally reported. (1)H NMR spectroscopic studies indicate that oxidative addition of GeH(4) to Ir(PPh(3))(2)(CO)Cl also occurs in a cis m...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
