504-55-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 504-55-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 504-55:
(5*5)+(4*0)+(3*4)+(2*5)+(1*5)=52
52 % 10 = 2
So 504-55-2 is a valid CAS Registry Number.

Preparation of functionalized dialkylzincs via a boron-zinc exchange. Reactivity and catalytic asymmetric addition to aldehydes

Langer, Falk,Schwink, Lothar,Devasagayaraj, Arokiasamy,Chavant, Pierre-Yves,Knochel, Paul

, p. 8229 - 8243 (2007/10/03)

The hydroboration of olefins with Et2BH provides diethyl(alkyl)boranes 2 which readily undergo a boron - zinc exchange with Et2Zn providing a range of polyfunctional primary, secondary, and benzylic diorganozincs. The resulting diorganozincs 3 have been reacted with various electrophiles (allylic halides, acid chlorides, alkylidenemalonates, ethyl propiolate, nitroolefins) in the presence of CuCN·2LiCl with excellent yields. With secondary dialkylzincs prepared from diastereomerically pure diethyl(alkyl)boranes, the boron-zinc exchange occurs with loss of stereochemistry. The asymmetric addition of 3 to aldehydes in the presence of the chiral catalyst 55 furnishes optically active polyfunctional secondary alcohols (50 to over 96% ee).
