Diethyl(phenylethynyl)phosphine oxide is a chemical compound with the molecular formula C14H15OP. It is an organophosphorus compound that features a phosphorus atom bonded to two ethyl groups and a phenylethynyl group. The phenylethynyl group consists of a phenyl ring (a benzene ring) attached to an ethynyl group (a carbon-carbon triple bond). diethyl(phenylethynyl)phosphine oxide is known for its potential applications in the synthesis of various organic compounds and as a ligand in coordination chemistry. It is also used in the preparation of other phosphorus-containing molecules, which can have applications in materials science, pharmaceuticals, and agrochemicals. The compound is typically synthesized through the reaction of diethylphosphine with phenylethynyl halides or through other organometallic reactions. It is an important intermediate in the preparation of more complex phosphorus-containing molecules due to its unique structure and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 7528-70-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,2 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7528-70:
(6*7)+(5*5)+(4*2)+(3*8)+(2*7)+(1*0)=113
113 % 10 = 3
So 7528-70-3 is a valid CAS Registry Number.

Unprecedented synthesis of alkynylphosphine-boranes through room-temperature oxidative alkynylation

Jouvin, Kevin,Veillard, Romain,Theunissen, Cedric,Alayrac, Carole,Gaumont, Annie-Claude,Evano, Gwilherm

, p. 4592 - 4595 (2013/09/24)

An original and user-friendly synthesis of alkynylphosphine-boranes, useful building blocks in organic synthesis, based on an oxidative P-alkynylation reaction with readily available copper acetylides is reported. The ability of a secondary phosphine protected with a borane to undergo oxidative coupling without oxidation of the P-moiety is demonstrated for the first time. The reaction, which proceeds at room temperature, is applicable to the preparation of enantioenriched and structurally complex alkynylphosphine-boranes.
