How many valence electrons does ch3 3sicl have?
. This ion has 18 valence electrons.
How do I delete a TMS group?
Most common deprotection methods
- TMS groups are susceptible to cleavage upon treatment with HF-based reagents. Tetrabutylammonium fluoride (Bu4NF) in THF. Fluorosilicic acid (H2SiF6)
- Treatment with HCl in THF/water solution.
What does TMSCl pyridine do?
TsCl and MsCl: Two Reagents That Convert Hydroxyl Groups (OH) Into Good Leaving Groups. Treatment of an alcohol with TsCl or MsCl, usually in the presence of a weak base such as pyridine, results in the sulfonate esters. (The purpose of pyridine is to mop up any HCl that is formed during the course of the reaction.)
What is thionyl chloride used for?
Thionyl chloride is mainly used in the industrial production of organochlorine compounds, which are often intermediates in pharmaceuticals and agrichemicals.
What is TMSCl reagent?
Trimethylsilyl chloride, also known as chlorotrimethylsilane is an organosilicon compound (silyl halide), with the formula (CH3)3SiCl, often abbreviated Me3SiCl or TMSCl. It is a colourless volatile liquid that is stable in the absence of water. It is widely used in organic chemistry.
How many valence electrons does SeF4 have?

Is TMS electron withdrawing?
Effects of Substituents effect: Trimethylsilyl (TMS) group shows high electron donating effect when it is at a carbon adjacent to -electron system (such as benzylic or allylic).
What is the protecting group for alcohol?
The most common protecting groups for alcohols are the silyl ethers. Here is the idea behind it. We take a silyl chloride, do a substitution using the alcohol as a nucleophile and then the alcohol converted into a silyl ether can be used in the presence of any strong base including the Grignard reagent.
What does TsCl and pyridine do to an alcohol?
