221129-42-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 221129-42-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,1,2 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 221129-42:
(8*2)+(7*2)+(6*1)+(5*1)+(4*2)+(3*9)+(2*4)+(1*2)=86
86 % 10 = 6
So 221129-42-6 is a valid CAS Registry Number.

Preparation of propargylic carbenoids and reactions with carbonyl compounds - A stereoselective synthesis of propargylic halohydrins and oxiranes

Chemla, Fabrice,Bernard, Nicolas,Ferreira, Franck,Normant, Jean F.

, p. 3295 - 3300 (2007/10/03)

The preparation and the reactivity of the zincioallene 3 is described, This organometallic compound reacts with aldehydes to yield propargylic halohydrins with good diastereoselectivities. These halohydrins can easily be converted into propargylic oxirane

Metalation of 3-trimethylsilyl propargyl chloride: A stereoselective access to trans-propargylic oxiranes

Chemla, Fabrice,Bernard, Nicolas,Normant, Jean F.

, p. 75 - 78 (2007/10/03)

The metalation of 3-trimethylsilyl-1-chloroprop-2-yne and the subsequent reaction with aldehydes affords stereospecifically anti-chlorohydrins which give after treatment with potassium fluoride and NaOH propargylic epoxides with good to excellent yields.
