Phosphonium, triethylmethyl-, iodide, also known as triethylmethylphosphonium iodide, is a quaternary phosphonium salt with the chemical formula (C2H5)3MeP+I-. It is a colorless, crystalline solid that is soluble in water and organic solvents. Phosphonium, triethylmethyl-, iodide is formed by the reaction of triethylmethylphosphine with iodine, resulting in the formation of a positively charged phosphonium ion and a negatively charged iodide ion. Triethylmethylphosphonium iodide is used as a phase-transfer catalyst in various organic synthesis reactions, particularly in the preparation of organometallic compounds and in the synthesis of pharmaceuticals. Its ability to facilitate the transfer of reactants between aqueous and organic phases makes it a valuable tool in the field of chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 7017-05-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,1 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7017-05:
(6*7)+(5*0)+(4*1)+(3*7)+(2*0)+(1*5)=72
72 % 10 = 2
So 7017-05-2 is a valid CAS Registry Number.

Chemistry of O-Alkyl Selenoesters. Reaction with Triethylphosphine

Hansen, Per-Egil

, p. 1627 - 1634 (2007/10/02)

The reaction between triethylphosphine and a number of aliphatic and aromatic selenoesters under oxygen-free conditions have been investigated.The purple intermediate formed in the reaction with the aliphatic selenoesters was quenched with atmospheric oxygen and gave the corresponding esters, whereas quenching with methyl iodide gave the corresponding 1-alkoxy-1-iodoalkyltriethylphosphonium iodides (13)-(16).The 1-alkoxy-1-iodoalkyltriethylphosphonium iodides gave the 1-alkoxyalkyltriethylphosphonium iodides (17)-(20) upon treatment with methanol, and treatment with benzaldehyde at -70 deg C gave α-alkoxyalkyl phenyl ketones (22)-(25).The reaction between the selenobenzoates and triethylphosphine gave α-dialkoxy-stilbenes and -dibenzyls.When the reaction was carried out in cyclohexene 7-alkoxy-7-phenylbicycloheptanes were formed.The presence of benzaldehyde in the reaction mixture led to α-alkoxystilbenes.An explanation for these different reactions is presented.
