77970-17-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77970-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,7 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77970-17:
(7*7)+(6*7)+(5*9)+(4*7)+(3*0)+(2*1)+(1*7)=173
173 % 10 = 3
So 77970-17-3 is a valid CAS Registry Number.

3-NITROCYCLOALKENONES, SYNTHESIS AND USE AS REVERSE AFFINITY CYCLOALKYNONE EQUIVALENTS

Corey, E. J.,Estreicher, Herbert

, p. 603 - 606 (1981)

A partical synthesis of 3-nitrocycloalkenones and their utilization as dienophiles in the Diels-Alder reaction are discribed.The results demonstrate a reverse affinity equivalency between these β-nitro-enones and "cycloalkynones".

An unprecedented method for the generation of tert -butylperoxy radical using DIB/TBHP protocol: Solvent effect and application on allylic oxidation

Zhao, Yi,Yeung, Ying-Yeung

supporting information; experimental part, p. 2128 - 2131 (2010/08/05)

Figure presented Tert-Butylperoxy radical was generated with PhI(OAc) 2 and tBuOOH. Ester solvent was found to be critical and the protocol was applied in the allylic oxidation of various olefinic substrates, which gave the corresponding α,β-unsaturated enones in good yield and regioselectivity.

Dirhodium(II) caprolactamate: An exceptional catalyst for allylic oxidation

Catino, Arthur J.,Forslund, Raymond E.,Doyle, Michael P.

, p. 13622 - 13623 (2007/10/03)

The oxidation of organic molecules represents a fundamentally important chemical process. Particularly important is allylic oxidation, whereby a single methylene unit is converted directly into a carbonyl group. In this communication, we report that dirhodium(II) caprolactamate [Rh2(cap)4] in combination with tert-butyl hydroperoxide (terminal oxidant) effectively catalyzes the allylic oxidation of a variety of olefins and enones. The reaction is completely selective, tolerant of air/moisture, and can be performed with as little as 0.1 mol % catalyst in minutes. A mechanistic proposal involving redox chain catalysis has been put forth, as well as evidence for the intermediacy of a higher valent dirhodium tert-butyl peroxy complex. Copyright
