83948-28-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83948-28-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,4 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83948-28:
(7*8)+(6*3)+(5*9)+(4*4)+(3*8)+(2*2)+(1*8)=171
171 % 10 = 1
So 83948-28-1 is a valid CAS Registry Number.

Lithium perchlorate mediated three component reaction for the preparation of primary amines

Saidi, Mohammad R.,Javanshir, Shahrzad,Mojtahedi, Mohammad M.

, p. 330 - 331 (1999)

In the presence of lithium perchlorate in diethyl ether, LPDE, a three- component reaction between aldehydes, sodium hexamethyldisilazane or lithium hexamethyldisilazane, LHMDS, and different nucleophiles proceeds smoothly to afford primary amines in good yields.

Access to nitriles from aldehydes mediated by an oxoammonium salt

Kelly, Christopher B.,Lambert, Kyle M.,Mercadante, Michael A.,Ovian, John M.,Bailey, William F.,Leadbeater, Nicholas E.

supporting information, p. 4241 - 4245 (2015/04/14)

A scalable, high yielding, rapid route to access an array of nitriles from aldehydes mediated by an oxoammonium salt (4-acetylamino-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate) and hexamethyldisilazane (HMDS) as an ammonia surrogate has been developed. The reaction likely involves two distinct chemical transformations: reversible silyl-imine formation between HMDS and an aldehyde, followed by oxidation mediated by the oxoammonium salt and desilylation to furnish a nitrile. The spent oxidant can be easily recovered and used to regenerate the oxoammonium salt oxidant.

Lithium perchlorate mediated three-component preparation of primaryaminoesters

Saidi, Mohammad R.,Azizi, Najmoddin

, p. 72 - 74 (2007/10/03)

A three-component reaction between an aldehyde, metallated hexamethyldisilazane and a functionalized organozinc compound proceeded smoothly in the presence of LiClO4 in diethyl ether to afford primary amino esters in good yields.
