20655-58-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20655-58-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,5 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20655-58:
(7*2)+(6*0)+(5*6)+(4*5)+(3*5)+(2*5)+(1*8)=97
97 % 10 = 7
So 20655-58-7 is a valid CAS Registry Number.

HOMOGENEOUS PALLADIUM-CATALYSED ARYLATION OF ACTIVATED ALKENES WITH ARYL CHLORIDES

Spencer, Alwyn

, p. 115 - 120 (1984)

A study has been made of arylation of activated alkenes with aryl chlorides homogeneously catalysed by palladium acetate in the presence of triphenylphosphine or tri-p-tolylphosphine.Electron-withdrawing substituents in the aryl chloride favour the reaction.Only moderate yields could be obtained, and the maximum turnover number was 51, mainly because of precipitation of palladium metal.The probable mechanism of the reaction is discussed.

Hypervalent iodine(iii) induced oxidative olefination of benzylamines using Wittig reagents

Ramavath, Vijayalakshmi,Rupanawar, Bapurao D.,More, Satish G.,Bansode, Ajay H.,Suryavanshi, Gurunath

, p. 8806 - 8813 (2021/05/26)

We have developed hypervalent iodine(iii) induced oxidative olefination of primary and secondary benzylamines using 2C-Wittig reagents, which provides easy access to α,β-unsaturated esters. Mild reaction conditions, good to excellent yields with high (E) selectivity, and a broad substrate scope are the key features of this reaction. We have successfully carried out the gram-scale synthesis of α,β-unsaturated esters.

1,3-Diphenyldisiloxane Enables Additive-Free Redox Recycling Reactions and Catalysis with Triphenylphosphine

Buonomo, Joseph A.,Cole, Malcolm S.,Eiden, Carter G.,Aldrich, Courtney C.

, p. 3583 - 3594 (2020/09/15)

The recently reported chemoselective reduction of phosphine oxides with 1,3-diphenyldisiloxane (DPDS) has opened up the possibility of additive-free phosphine oxide reductions in catalytic systems. Herein we disclose the use of this new reducing agent as an enabler of phosphorus redox recycling in Wittig, Staudinger, and alcohol substitution reactions. DPDS was successfully utilized in ambient-temperature additive-free redox recycling variants of the Wittig olefination, Appel halogenation, and Staudinger reduction. Triphenylphosphine-promoted catalytic recycling reactions were also facilitated by DPDS. Additive-free triphenylphosphine-promoted catalytic Staudinger reductions could even be performed at ambient temperature due to the rapid nature of phosphinimine reduction, for which we characterized kinetic and thermodynamic parameters. These results demonstrate the utility of DPDS as an excellent reducing agent for the development of phosphorus redox recycling reactions.
