Synthesis and reactivity of silylated tetrathiafulvalenes.

Novel organosilylated tetrathiafulvalenes (TTFs) possessing Si-H or Si-Si bonds have been synthesised. The crystal structures of several derivatives have been determined by X-ray diffraction, including that of dimeric (Si2Me4)(TTF)2 (11) incorporating a diatomic SiMe2-SiMe2 linker. Cyclic voltammetry measurements in all cases show two oxidation waves. DFT calculations were performed to rational...

Access to Orthogonal Protected Phenols – Synthesis of a Silylated Quinol

In the course of studies towards the total synthesis of Elisabethin A (1), it was necessary to elaborate a synthetic strategy for a quinol which is protected orthogonally to a methylether. Elisabethin A is a natural product which was isolated from the Caribbean gorgonian Pseudopterogorgia elisabethae (Octocorallia) [1]. Marine natural products are among the most promising sources of new biologi...

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...

Convergent synthesis of silylated allylic alcohols by a stereoselective domino, sequential radical-coupling reaction.

General. 1H and C NMR spectra were measured on Varian Gemini 2000 (300 MHz for H) instruments, and are reported in parts per million (δ) from internal tetramethylsilane or residual solvent peak. IR spectra were recorded on a Shimadzu FTIR-8200, and absorptions are reported in cm. FAB-MS spectra were recorded on JEOL IMS-300 spectrometer. 3-Nitrobenzyl alcohol was used as a matrix for FAB-MS. Me...

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
