Physical properties
mp 144–145°C.Uses
Bis(β-trimethylsilylethanesulfonyl)imide is a useful reagent for the preparation of protected amines.Preparation
Bis(β-trimethylsilylethanesulfonyl)imide is easily obtained via a two-step sequence starting from the reaction of commercially available methanesulfonyl chloride and ammonium chloride in the presence of sodium hydroxide (eq 1).The product bis(methanesulfonimide) (1) is then treated with equiv ofLiHMDSat?78°C to give a trianion. Subsequent alkylation with equiv of commercially available (iodomethyl)trimethylsilane andwarming to room temperature affords the desired sulfonimide in good yield (eq 1).Check Digit Verification of cas no
The CAS Registry Mumber 548462-13-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,8,4,6 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.Calculate Digit Verification of CAS Registry Number 548462-13:
(8*5)+(7*4)+(6*8)+(5*4)+(4*6)+(3*2)+(2*1)+(1*3)=171
171 % 10 = 1
So 548462-13-1 is a valid CAS Registry Number.
