4342-22-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4342-22-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,4 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4342-22:
(6*4)+(5*3)+(4*4)+(3*2)+(2*2)+(1*2)=67
67 % 10 = 7
So 4342-22-7 is a valid CAS Registry Number.

Nanoparticulate intermetallic compound Ni3Ga supported on SiO2has emerged as a highly efficient catalyst for the hydrosilylation of carbonyls, such as aldehydes and ketones, at room temperature. Formation of electron-enriched Niviaal

One-Pot Synthesis of Silylated Enol Triflates from Silyl Enol Ethers for Cyclohexynes and 1,2-Cyclohexadienes

Inoue, Kazuki,Nakura, Ryo,Okano, Kentaro,Mori, Atsunori

supporting information, p. 3343 - 3347 (2018/07/13)

Regiocontrolled synthesis of precursors for strained cyclohexynes and 1,2-cyclohexadienes is described based on one-pot rearrangement of silyl enol ether followed by formation of enol triflate. Treatment of silyl enol ether with a combination of LDA and tBuOK led to the migration of the silyl group to generate α-silyl enolate, which was treated with Comins' reagent to provide the corresponding enol triflate. The transient α-silylated lithium enolate was smoothly isomerized in the presence of stoichiometric amount of water within one hour at room temperature, providing precursors for cyclohexynes exclusively in one pot. Effects of silyl groups, isomerization of the lithium enolate, and regiocontrolled generation of these precursors for these strained molecules were also investigated.

Photo Lewis acid generators: Photorelease of B(C6F5)3 and applications to catalysis

Khalimon, Andrey Y.,Shaw, Bryan K.,Marwitz, Adam J. V.,Piers, Warren E.,Blackwell, James M.,Parvez, Masood

supporting information, p. 18196 - 18206 (2015/10/28)

A series of molecules capable of releasing of the strong organometallic Lewis acid B(C6F5)3 upon exposure to 254 nm light have been developed. These photo Lewis acid generators (PhLAGs) can now serve as photoinitiators for several important B(C6F5)3-catalyzed reactions. Herein is described the synthesis of the triphenylsulfonium and diphenyliodonium salts of carbamato- and hydridoborates, their establishment as PhLAGs, and studies aimed at defining the mechanism of borane release. Factors affecting these photolytic reactions and the application of this concept to photoinduced hydrosilylation reactions and construction of siloxane scaffolds are also discussed.
