4923-85-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4923-85-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,2 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4923-85:
(6*4)+(5*9)+(4*2)+(3*3)+(2*8)+(1*5)=107
107 % 10 = 7
So 4923-85-7 is a valid CAS Registry Number.

Reactivity of allyl anions of allylphosphine-boranes towards electrophiles

Stankevic, Marek,Siek, Marcin,Pietrusiewicz, K. Michal

experimental part, p. 102 - 126 (2011/06/20)

The reactivity of mesomeric carbanions derived from allylphosphine-boranes varies as a function of electrophile. Small sp3-electrophiles react predominantly at the α carbon atom whereas bulky sp3- electrophiles and carbonyl compounds react mainly at the γ carbon. In the case of electron-deficient aldehydes reduction of carbonyl group and formation of the corresponding alcohols is observed. This is attributed to the weakly reducing properties of carbanions derived from allylphosphine-boranes, whose mesomeric form resembles the structure of a modified borohydride. ARKAT-USA, Inc.

MECHANISM OF THE CHLOROLYSIS REACTION OF P-S BOND IN PHOSPHORUS THIOLOESTERS. THE EFFECT OF THE SUBSTITUENT AT SULFUR ATOM ON THE STEREOCHEMISTRY

Krawiecka, Bozena,Wojna-Tadeusiak, Elzbieta

, p. 69 - 72 (2007/10/02)

The effect of the substituent at sulfur atom on the stereochemistry of the chlorolysis reaction of P-S bond in phosphorus thioloesters was studied.It was found that the presence of the substituents lowering electron density at this atom reduces the reacti

SILYLPEROXIDES AS SELECTIVE OXYGENATION REAGENTS IN PHOSPHORUS CHEMISRTY

Kowalski, Jozef,Wozniak, Lucyna,Chojnowski, Julian

, p. 125 - 128 (2007/10/02)

Bis(trimethylsilyl)peroxide (BSPO) can be used for chemo- and stereoselective generation of P=O group by oxygenation of P(III) centre and transformation of P=S and P=Se groups.
