25979-07-1 Usage

Chemical Properties

white to light yellow crystal powde

Uses

Reactant for the synthesis of alkali metal complexes. As intermediates. tert-Butyldichlorophosphine (TBDCP) is used primarily in the preparation of monoand bidentate phosphine ligands in metal complexes for catalytic chiral asymmetric hydrogenations and other asymmetric reactions as well as transition metal coupling reactions. This reagent is also used in the preparation of other phosphines in catalytic polymerization reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 25979-07-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,7 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25979-07:
(7*2)+(6*5)+(5*9)+(4*7)+(3*9)+(2*0)+(1*7)=151
151 % 10 = 1
So 25979-07-1 is a valid CAS Registry Number.

A new and convenient approach for the synthesis of P-stereogenic intermediates bearing a tert-butyl(methyl)phosphino group

Liu, Yang,Ding, Boqiang,Liu, Delong,Zhang, Zhenfeng,Liu, Yangang,Zhang, Wanbin

, p. 4959 - 4966 (2017)

Chiral organophosphorus compounds possessing a P-stereogenic center have been widely used as agricultural chemicals, pharmaceuticals, organocatalysts, and ligands for transition-metal catalysis. P-Stereogenic intermediates bearing a tert-butyl(methyl)phosphino group are important for the preparation of several commonly used diphosphine ligands. However, previously reported synthetic methods used hazardous starting materials and are difficult to operate. In order to overcome these limitations, a new and convenient synthesis for a number of P-stereogenic intermediates possessing a tert-butyl(methyl)phosphino group has been developed. The reported route relies on an air- and moisture-stable secondary phosphine oxide prepared from a readily available starting material, trichlorophosphane.
