General Description

"(2R,4S,5R)-(+)-2,5-DIPHENYL-3,4-DIMETHYL-1,3,2-OXAZAPHOSPHOLIDINE-2-BORANE" is a chiral boron compound that is often used as a reagent in organic synthesis. It is an oxazaphospholidine derivative with two phenyl groups, two methyl groups, and a boron atom attached to a heterocyclic phospholine ring. (2R,4S,5R)-(+)-2,5-DIPHENYL-3,4-DIMETHYL-1,3,2-OXAZAPHOSPHOLIDINE-2-BORANE is commonly utilized as a catalyst in asymmetric synthesis reactions, particularly in the formation of carbon-carbon and carbon-heteroatom bonds. Its three-dimensional arrangement of atoms allows for selective and efficient transformations in various chemical reactions, making it a valuable tool in the synthesis of pharmaceuticals and other organic compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 130666-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,6 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130666-29:
(8*1)+(7*3)+(6*0)+(5*6)+(4*6)+(3*6)+(2*2)+(1*9)=114
114 % 10 = 4
So 130666-29-4 is a valid CAS Registry Number.

Homometathesis and cross-metathesis coupling of phosphine-borane templates with electron-rich and electron-poor olefins

Dunne, Katherine S.,Lee, Sarah E.,Gouverneur, Véronique

, p. 5246 - 5259 (2007/10/03)

Ruthenium-catalysed olefin cross-metathesis can be used to synthesise structurally diverse acyclic phosphines protected as their borane complexes. Homodimerisations have been investigated and proved successful only for the allyl-substituted borane-protected phosphines. In the presence of various olefinic partners, allyl-substituted P templates reacted in cross-couplings to give predominantly the E products but traces of the Z isomers were always detected in the crude reaction mixtures. In contrast, cross-metathesis of vinyl-substituted phosphine boranes took place with exclusive E-selectivity. Although the conversions were consistently very good to excellent, the yields of purified products were often significantly lower suggesting that some of the newly formed compounds are prone to decompose upon purification.
