21965-92-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21965-92-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,6 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21965-92:
(7*2)+(6*1)+(5*9)+(4*6)+(3*5)+(2*9)+(1*2)=124
124 % 10 = 4
So 21965-92-4 is a valid CAS Registry Number.

Visible Light-Mediated Direct Decarboxylative C-H Functionalization of Heteroarenes

Garza-Sanchez, R. Aleyda,Tlahuext-Aca, Adrian,Tavakoli, Ghazal,Glorius, Frank

, p. 4057 - 4061 (2017/06/19)

The direct visible light-mediated C-H alkylation of heteroarenes using aliphatic carboxylic acids is reported. This mild method proceeds at low catalyst loadings (0.5 mol %) and has a high functional group tolerance and a broad substrate scope. Notably, f

Sunflow: Sunlight Drives Fast and Green Photochemical Flow Reactions in Simple Microcapillary Reactors – Application to Photoredox and H-Atom-Transfer Chemistry

Nauth, Alexander M.,Lipp, Alexander,Lipp, Benjamin,Opatz, Till

supporting information, p. 2099 - 2103 (2017/04/24)

“Sunflow“ – The combination of a microcapillary reactor in continuous flow mode with sunlight as the most sustainable energy source imaginable was applied to a range of photoredox and H-atom-transfer reactions making them both fast and green.

Transition-Metal-Free Decarboxylative Photoredox Coupling of Carboxylic Acids and Alcohols with Aromatic Nitriles

Lipp, Benjamin,Nauth, Alexander M.,Opatz, Till

, p. 6875 - 6882 (2016/08/16)

A transition-metal-free protocol for the redox-neutral light-induced decarboxylative coupling of carboxylic acids with (hetero)aromatic nitriles at ambient temperature is presented. A broad scope of acids and nitriles is accepted, and alcohols can be coupled in a similar fashion through their oxalate half esters. Various inexpensive sources of UV light and even sunlight can be used to achieve this C-C bond formation proceeding through a free radical mechanism.
