4762-28-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4762-28-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,6 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4762-28:
(6*4)+(5*7)+(4*6)+(3*2)+(2*2)+(1*8)=101
101 % 10 = 1
So 4762-28-1 is a valid CAS Registry Number.

Phosphinoyl Radical Initiated Vicinal Cyanophosphinoylation of Alkenes

Zhang, Pei-Zhi,Zhang, Ling,Li, Jian-An,Shoberu, Adedamola,Zou, Jian-Ping,Zhang, Wei

supporting information, p. 5537 - 5540 (2017/10/25)

A double-functionalization reaction of alkenes through Mn(OAc)3-mediated phosphinoyl radical addition followed by CuCN-catalyzed cyanation is introduced. This one-pot reaction is performed under mild conditions to afford vicinal cyanophosphinoylation products.

Hydrophosphinylation of unactivated alkenes with secondary phosphine oxides under visible-light photocatalysis

Yoo, Woo-Jin,Kobayashi, Shu

supporting information, p. 1844 - 1848 (2013/09/24)

A visible light induced hydrophosphinylation of unactivated alkenes with diaryl phosphine oxides was found to occur with good yields and under mild reaction conditions in the presence of an inexpensive and commercially available organic dye as a photocatalyst.

Air-induced anti-Markovnikov addition of secondary phosphine oxides and H-phosphinates to alkenes

Hirai, Takayoshi,Han, Li-Biao

, p. 53 - 55 (2007/10/03)

(Chemical Equation Presented) Air (oxygen) induces the addition of secondary phosphine oxides and H-phosphinates to alkenes to selectively produce the corresponding anti-Markovnikov adducts in good to high yields. Mechanistic studies show that the addition probably proceeds via a radical chain mechanism.

ALKYLATION IN SITU OF ARYLPHOSPHINES FORMED DURING THERMOLYSIS OF HYDROPHOSPHORYL COMPOUNDS

Chauzov, V. A.,Kostina, L. P.

, p. 2026 - 2031 (2007/10/02)

In the course of the thermolysis (ca. 200 deg C) of diorganophosphonous and phenylphosphonous acids in the presence of alkyl halides, polyalkylation products are obtained - dialkyldiphenyl- and trialkylphenylphosphonium salts and dialkylphenylphosphine oxides.Combined with alkaline splitting of the phosphonium salts, it is possible to synthesize dialkylphenyl- and trioctylphosphine oxides from available hydrophosphoryl compounds using these reactions.
