312-92-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 312-92-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,1 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 312-92:
(5*3)+(4*1)+(3*2)+(2*9)+(1*2)=45
45 % 10 = 5
So 312-92-5 is a valid CAS Registry Number.

Bu4N+ alkoxide-initiated/autocatalytic addition reactions with organotrimethylsilanes

Das, Manas,O'Shea, Donal F.

, p. 5595 - 5607 (2014/07/08)

The use of Me3SiO-/Bu4N+ as a general activator of organotrimethylsilanes for addition reactions has been established. The broad scope of the method offers trimethylsilanes (including acetate, allyl, propargyl, benzyl, dithiane, heteroaryl, and aryl derivatives) as bench-stable organometallics that can be readily utilized as carbanion equivalents for synthesis. Reactions are achieved at rt without the requirement of specialized precautions that are commonplace for other organometallics.

Rhodium-catalyzed silylation and intramolecular arylation of nitriles via the silicon-assisted cleavage of carbon-cyano bonds

Tobisu, Mamoru,Kita, Yusuke,Ano, Yusuke,Chatani, Naoto

supporting information; experimental part, p. 15982 - 15989 (2009/05/16)

A rhodium-catalyzed silylation reaction of carbon - cyano bonds using disilane has been developed. Under these catalytic conditions, carbon-cyano bonds in aryl, alkenyl, allyl, and benzyl cyanides bearing a variety of functional groups can be silylated. The observation of an enamine side product in the silylation of benzyl cyanides and related stoichiometric studies indicate that the carbon-cyano bond cleavage proceeds through the deinsertion of silyl isocyanide from η2-iminoacyl complex B. Knowledge gained from these studies has led to the development of a new intramolecular biaryl coupling reaction in which aryl cyanides and aryl chlorides are cross-coupled.

Synthese d'aryl- et heteroarylsilanes par scission de l'hexamethyldisilane
