5929-67-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5929-67-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,2 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5929-67:
(6*5)+(5*9)+(4*2)+(3*9)+(2*6)+(1*7)=129
129 % 10 = 9
So 5929-67-9 is a valid CAS Registry Number.

Palladium-catalyzed hydrophosphonylation of alkenes with dialkyl H-phosphonates

Candy, Mathieu,Rousseaux, Sophie A. L.,Sanroman, Alberto Cirugeda,Szymczyk, Monika,Kafarski, Pawel,Leclerc, Eric,Vrancken, Emmanuel,Campagne, Jean-Marc

The palladium-catalyzed hydrophosphonylation of alkenes with previously unreactive acyclic dialkyl H-phosphonates has been developed. A catalyst system based on palladium/DavePhos or palladium/SPhos enables the transformation of various alkenes to phospho

Hydrophosphorylation of alkenes with dialkyl phosphites catalyzed by Mn(III) under air

Tayama, Osamu,Nakano, Atsushi,Iwahama, Takahiro,Sakaguchi, Satoshi,Ishii, Yasutaka

, p. 5494 - 5496 (2007/10/03)

A facile method for the synthesis of organophosphonates from alkenes and dialkyl phosphites was developed by the use of Mn(II) under air. Thus, the reaction of 1-octene with diethyl phosphite in the presence of Mn(OAc) 2 (5 mol %) under air at 90 °C led to diethyl octylphosphonate (78%) and diethyl (2-hexyl)decylphosphonate (6%). Internal alkenes such as cis-2-octene gave a regioisomeric mixture of the corresponding hydrophosphorylation products in 84% yields.
