Tris{(+)-1-phenylethoxy}borane, also known as (+)-Ipc2BH, is a chiral borane reagent used in organic chemistry. It is a derivative of borane, with three (+)-1-phenylethoxy groups attached to the boron atom. tris{(+)-1-phenylethoxy}borane is known for its ability to act as a reducing agent, particularly in the asymmetric reduction of ketones to produce chiral alcohols. The (+)-1-phenylethoxy groups confer chirality to the borane, which can be crucial in the synthesis of enantiomerically pure compounds. Its applications are primarily in the field of asymmetric synthesis, where the selective formation of one enantiomer over another is desired. The reagent is also valued for its stability and ease of handling compared to other borane reagents.

Check Digit Verification of cas no

The CAS Registry Mumber 29002-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,0,0 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 29002-72:
(7*2)+(6*9)+(5*0)+(4*0)+(3*2)+(2*7)+(1*2)=90
90 % 10 = 0
So 29002-72-0 is a valid CAS Registry Number.

Sodium Aminodiboranate, a New Reagent for Chemoselective Reduction of Aldehydes and Ketones to Alcohols

Wang, Jin,Guo, Yu,Li, Shouhu,Chen, Xuenian

supporting information, p. 1104 - 1108 (2021/05/25)

Sodium aminodiboranate (NaNH 2(BH 3) 2, NaADBH) is a new member of the old borane family, which exhibits superior performance in chemoselective reduction. Experimental results show that NaADBH can rapidly reduce aldehydes and ketones to the corresponding alcohols in high efficiency and selectivity under mild conditions. There are little steric and electronic effects on this reduction.

Ammonia borane as a metal free reductant for ketones and aldehydes: A mechanistic study

Yang, Xianghua,Fox, Thomas,Berke, Heinz

experimental part, p. 7121 - 7127 (2011/10/05)

Without a catalyst ketones and aldehydes were reacted in THF with ammonia borane (AB) to proceed hydroboration forming alkyl borates. Mechanistic studies revealed that dissociation of ammonia from AB occurred before the hydroboration step. When methanol was used as the solvent, metal free methanolysis of AB would take place with the ketone/aldehyde being directly hydrogenated by the MeOH·BH3 complex.
