Purification Methods
Wash it with distilled H2O and dry it in a vacuum. Dissolve it in ca 5 parts of hot dioxane and cool to give orange crystals m 181-183o. Recrystallisation from *C6H6/heptane (1:2) gives a product with m 183-184o. [Bishop et al. J Organomet Chem 27 241 1971.]
Check Digit Verification of cas no
The CAS Registry Mumber 12150-46-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,5 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 12150-46:
(7*1)+(6*2)+(5*1)+(4*5)+(3*0)+(2*4)+(1*6)=58
58 % 10 = 8
So 12150-46-8 is a valid CAS Registry Number.

FERROCENOPHANES WITH PHOSPHORUS AND ARSENIC AS THE BRIDGING ATOMS: SYNTHESIS AND SOME REACTIONS. A NEW ROUTE TO FERROCENYLLITHIUM REAGENTS
Seyferth, Dietmar,Withers, Howard P.
, p. C1 - C5 (1980)
(1,1'-Ferrocenediyl)phenyl-phosphine and -arsine and (1,1'-ferrocenediyl)-methylphosphine have been prepared by the reaction of 1,1'-dilithioferrocenetetramethylethylenediamine with the respective RPCl2 and PhAsCl2.They react at the Group V bridging atom with sulfur and with reactive metal carbonyl species without disruption of the ferrocenophane system.Organolithium reagents react with these compounds to open the ring and give 1-lithio-1'-phosphino- or arsino-ferrocenes.Some reactions of these new lithium reagents are reported.
Metal-Free Reduction of Phosphine Oxides, Sulfoxides, and N-Oxides with Hydrosilanes using a Borinic Acid Precatalyst
Chardon, Aurélien,Maubert, Orianne,Rouden, Jacques,Blanchet, Jér?me
, p. 4460 - 4464 (2017/11/22)
The general reduction of phosphine oxides, sulfoxides, and amine N-oxides was achieved by combining bis(2-chlorophenyl)borinic acid with phenylsilane. The reaction was shown to tolerate a wide range of substrates and could be performed under mild conditions, with only 2.5 mol % of the easily synthesized catalyst. Mechanistic investigations pointed to a key borohydride as the real catalyst and at bis(2-chlorophenyl)borinic acid as a precatalyst.

, p. 1156 - 1160 (2015/06/30)
Reduction of tertiary phosphine oxides and sulfides into the corresponding phosphines with amine-assisted aluminum hydrides has been studied. The method is characterized by mild conditions, short reaction time, high efficiency, and expanded substrate scope. The new method is an alternative to the currently used methods of reducing phosphine oxides or recycling phosphines engaged in organic reactions.
