(3-bromobenzyl)trimethylsilane is an organosilicon compound characterized by a benzyl group (C6H5-CH2-) with a bromine atom attached at the 3rd carbon position, and a trimethylsilyl group (Si(CH3)3) attached to the benzyl group. This chemical is often used as a protecting group in organic synthesis, particularly for the selective protection of benzyl alcohols and amines. It is also employed in the synthesis of various pharmaceuticals and agrochemicals due to its ability to stabilize reactive intermediates and facilitate specific chemical transformations. The compound is known for its stability and reactivity, which makes it a valuable tool in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 1833-43-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1833-43:
(6*1)+(5*8)+(4*3)+(3*3)+(2*4)+(1*3)=78
78 % 10 = 8
So 1833-43-8 is a valid CAS Registry Number.

Synthesis of Polysubstituted Iodoarenes Enabled by Iterative Iodine-Directed para and ortho C?H Functionalization

Wu, Yichen,Bouvet, Sébastien,Izquierdo, Susana,Shafir, Alexandr

, p. 2617 - 2621 (2019)

Among halogenated aromatics, iodoarenes are unique in their ability to produce the bench-stable halogen(III) form. Earlier, such iodine(III) centers were shown to enable C?H functionalization ortho to iodine via halogen-centered rearrangement. The broader implications of this phenomenon are explored by testing the extent of an unusual iodane-directed para C?H benzylation, as well as by developing an efficient C?H coupling with sulfonyl-substituted allylic silanes. Through the combination of the one-shot nature of the coupling event and the iodine retention, multisubstituted arenes can be prepared by sequentially engaging up to three aromatic C?H sites. This type of iodine-based iterative synthesis will serve as a tool for the formation of value-added aromatic cores.
