701-03-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 701-03-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,0 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 701-03:
(5*7)+(4*0)+(3*1)+(2*0)+(1*3)=41
41 % 10 = 1
So 701-03-1 is a valid CAS Registry Number.

CsOH-promoted P-alkylation: A convenient and highly efficient synthesis of tertiary phosphines

Honaker, Matthew T.,Sandefur, Benjamin J.,Hargett, James L.,McDaniel, Alicia L.,Salvatore, Ralph Nicholas

, p. 8373 - 7377 (2007/10/03)

A mild and efficient method for the synthesis of tertiary phosphines and ditertiary phosphines has been developed. In the presence of cesium hydroxide, molecular sieves and DMF at room temperature, various secondary phosphines and alkyl bromides were examined, and the results have demonstrated that this methodology offers a general synthetic procedure to produce tertiary phosphines in moderate to high yields. Optically active tertiary phosphine synthesis is also described.

Preparation of Alkylmethylphenylphosphines by the Method of Hewertson and Watson

Wolfsberger, Werner

, p. 295 - 298 (2007/10/02)

The reaction of C6H5(CH3)PNa with some alkyl halides in liquid ammonia was studied.The resulting phosphines were characterized by elemental analyses, NMR spectra, and by the reaction with trimethylsilyl azide giving trimethylsilylimino triorganophosphoranes. - Keywords: Alkylmethylphenylphosphines, N-Trimethylsilylimino Triorganophosphoranes, NMR Spectra

A GENERAL SYNTHESIS OF OPTICALLY ACTIVE PHOSPHINES, PHOSPHINITES AND THIOPHOSPHINITES FROM ALKYLTHIO(ALKYLSELENO)PHOSPHONIUM SALTS AND TRIS(DIMETHYLAMINO)PHOSPHINE AS A THIOPHILIC AGENT

Omelanczuk, J.,Mikolajczyk, M.

, p. 2493 - 2496 (2007/10/02)

Tris(dimethylamino)phosphine was found to be a suitable thiophilic reagent which converts optically active alkylthio(alkylseleno)phosphonium salts into chiral tertiary phosphines and phosphonites with a high stereoselectivity.The first synthesis of optically active thiophosphinites from bis(alkylthio)phosphonium salts and tris(dimethylamino)phosphine is also reported.
