2845-43-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2845-43-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,4 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2845-43:
(6*2)+(5*8)+(4*4)+(3*5)+(2*4)+(1*3)=94
94 % 10 = 4
So 2845-43-4 is a valid CAS Registry Number.

A NOVEL AMINOMETHYLATION OF SILYL ENOL ETHERS WITH AMINOMETHYL ETHERS CATALYZED BY IODOTRIMETHYLSILANE OR TRIMETHYLSILYL TRIFLUOROMETHANESULFONATE

Hosomi, Akira,Iijima, Susumu,Sakurai, Hideki

, p. 547 - 550 (1982)

The iodotrimethylsilane-catalyzed reaction of silyl enol ethers with aminomethyl ethers in acetonitrile gives aminomethylation products of the corresponding ketones readily.The reaction can also be catalyzed by trimethylsilyl trifluoromethanesulfonate in dichloromethane.

Dibromomethane as one-carbon source in organic synthesis: Microwave-accelerated α-methylenation of ketones with dibromomethane and diethylamine

Hon, Yung-Son,Hsu, Tzyy-Rong,Chen, Chun-Yan,Lin, Yi-Hui,Chang, Fong-Jong,Hsieh, Cheng-Han,Szu, Ping-Hui

, p. 1509 - 1520 (2007/10/03)

The reactivity of aryl alkyl ketone with a preheated mixture of dibromomethane and diethylamine is poor and gives an α-methylenation product in very low yield even under refluxing condition. It can be accelerated dramatically by microwave irradiation. Under microwave condition, the cyclic 1,3-dicarbonyls, aryl alkyl ketones, heteroaryl alkyl ketones and acyclic benzyl ketone give α-methylenation products in modest to good yields.
