N-butyldicyclohexylphosphine oxide, also known as 1-butyl-1,2-dicyclohexylphosphine oxide, is an organophosphorus compound with the chemical formula C14H27OP. It is a colorless to pale yellow liquid at room temperature and is soluble in common organic solvents. n-butyldicyclohexylphosphine oxide is primarily used as a ligand in various chemical reactions, particularly in the synthesis of transition metal complexes. It is also employed as a reagent in the preparation of other organophosphorus compounds and as a stabilizer in the production of certain polymers. Due to its potential toxicity and reactivity, it is essential to handle n-butyldicyclohexylphosphine oxide with care and in accordance with safety guidelines.

Check Digit Verification of cas no

The CAS Registry Mumber 2959-64-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,5 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2959-64:
(6*2)+(5*9)+(4*5)+(3*9)+(2*6)+(1*4)=120
120 % 10 = 0
So 2959-64-0 is a valid CAS Registry Number.

The reactivity of arylphosphine oxides under Bouveault-Blanc reaction conditions

Korzeniowska, Ewelina,Kozio?, Anna E.,?astawiecka, El?bieta,Flis, Anna,Stankevi?, Marek

Treatment of tertiary arylphosphine oxides with alkali metal/alcohol reagent system lead to the corresponding cyclohexyl-substituted phosphine oxides. This transformation makes use of the inexpensive sodium as the electron donor and an alcohol as the proton source, and provides an attractive alternative to reactions mediated by expensive transition metals. Under optimized conditions numerous mono- and diaryl substituted phosphine oxides were transformed into the corresponding mono- and dicyclohexyl-substituted phosphine oxides in good yields. Furthermore, the formation of 1,2-bis(phosphinoyl)cyclohexanes or unknown 5,10-dialkyltetradecahydrophosphanthrene 5,10-dioxides as side products was observed, which are hardly accessible by other procedures.
