Methyl[bis(trifluoromethyl)]phosphane, also known as trimethyl phosphite or MeP(CF3)2, is an organophosphorus compound with the chemical formula C3H3F6P. It is a colorless, volatile liquid that is soluble in organic solvents. methyl[bis(trifluoromethyl)]phosphane is primarily used as a precursor in the synthesis of various organophosphorus compounds, such as pesticides, flame retardants, and other specialty chemicals. Methyl[bis(trifluoromethyl)]phosphane is also employed as a ligand in organometallic chemistry, particularly in the formation of transition metal complexes. Due to its reactivity and potential health and environmental risks, it is essential to handle this chemical with proper safety measures and precautions.

1605-54-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1605-54-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1605-54:
(6*1)+(5*6)+(4*0)+(3*5)+(2*5)+(1*4)=65
65 % 10 = 5
So 1605-54-5 is a valid CAS Registry Number.

P-bis(trifluoromethyl) ylides: Synthesis and reactions

Dieckbreder, Uwe,Roeschenthaler, Gerd-Volker,Kolomeitsev, Alexander A.

, p. 650 - 653 (2002)

The methylation of bis(trifluoromethyl)phosphines by MeOSO2CF3, yielding the respective phosphonium salts was described. Methylation was done using methyl triflate at 100 °C without a solvent. It was found that deprotonation using MeN = P(NEt2)3 led to the phosphorus ylides stable in solution at ambient temperatures, which could be converted into 1,2λ5σ5-oxphosphetanes by adding hexafluoroacetone.

Advances in trifluoromethylating phosphorus compounds

, p. 597 - 600 (2007/10/03)

The System CF3IMe3P is re-investigated and Me2PCF3, Me4P+I-, (CF3)2PMe3, Me3PI2, [Me3(CF3)P]+I- are found as products. Using CF3Br/P(NEt2)3 the phosphines R12PCF3 and R1P(CF3)2 (e.g. R1 = Me, iPr, NEt2) can be obtained which are precursors either for phosphoranes (e.g. 1,2λ5σ5-oxaphosphetanes) or phosphonium salts (e.g. [R12(Me)PCF3]+X- or [R1(Me)P(CF3)2X-]. The latter are deprotonated to furnish methylene phosphoranes R12(CH2=)PCF3 or R1(CH2=)P(CF3)2, reactive synthons. From CF3Br/ P(NEt2)3/P(OPh)3 the phosphine P(CF3)3 is available, which turned out to be a potent electrophile. Amido phospites ROP(NEt2)2 and halides R2X (R2= CCl2CF3, X= Cl; R2= CF=CFCF3, X= F; R2= C6F5, X= Br, I; R2= C(CF3)3, X= Br; R2= SCF3, X= CF3) undergo an ARBUZOV reaction.
