Trifluoromethyltrimethylphosphonium iodide is a phosphonium salt with the chemical formula (CH3)3P+CF3I-. It is a colorless, crystalline solid that is soluble in organic solvents. trifluormethyltrimethylphosphoniumiodid is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-fluorine bonds. It is also employed as a catalyst in various chemical reactions, such as the Wittig reaction, which is used to synthesize alkenes. The compound is synthesized by the reaction of trifluoromethyl iodide with trimethyl phosphine. Due to its reactivity and potential hazards, it is important to handle this chemical with care, following appropriate safety protocols.

354-46-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 354-46-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 354-46:
(5*3)+(4*5)+(3*4)+(2*4)+(1*6)=61
61 % 10 = 1
So 354-46-1 is a valid CAS Registry Number.

Advances in trifluoromethylating phosphorus compounds

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.
