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.
Chemoselective Reduction of Phosphine Oxides by 1,3-Diphenyl-Disiloxane

Reduction of phosphine oxides to the corresponding phosphines represents the most straightforward method to prepare these valuable reagents. However, existing methods to reduce phosphine oxides suffer from inadequate chemoselectivity due to the strength of the P=O bond and/or poor atom economy. Herein, we report the discovery of the most powerful chemoselective reductant for this transformation to date, 1,3-diphenyl-disiloxane (DPDS). Additive-free DPDS selectively reduces both secondary and tertiary phosphine oxides with retention of configuration even in the presence of aldehyde, nitro, ester, α,β-unsaturated carbonyls, azocarboxylates, and cyano functional groups. Arrhenius analysis indicates that the activation barrier for reduction by DPDS is significantly lower than any previously calculated silane reduction system. Inclusion of a catalytic Br?nsted acid further reduced the activation barrier and led to the first silane-mediated reduction of acyclic phosphine oxides at room temperature.

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.
