Description
4-Cyanobenzophenone is a benzophenone derivative characterized by its slightly yellow crystalline powder appearance. It can be synthesized by treating 4-cyanobenzoyl chloride with benzene, and its reduction under electrochemical conditions results in the formation of 4-t-butyl-benzophenone and 1-(4-cyanophenyl)-2,2-dimethyl-1-phenylpropan-1-ol. 4-CYANOBENZOPHENONE is known for its efficiency as a triplet sensitizer in the photoisomerization of norbornadiene (N) to quadricyclane (Q) and vice versa.

Check Digit Verification of cas no
The CAS Registry Mumber 1503-49-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,0 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1503-49:
(6*1)+(5*5)+(4*0)+(3*3)+(2*4)+(1*9)=57
57 % 10 = 7
So 1503-49-7 is a valid CAS Registry Number.

Recyclable and Reusable Pd(OAc)2/XPhos–SO3Na/PEG-400/H2O System for Cyanation of Aryl Chlorides with Potassium Ferrocyanide

Pd(OAc)2/XPhos–SO3Na in a mixture of poly(ethylene glycol) (PEG-400) and water is shown to be a highly efficient catalyst for the cyanation of aryl chlorides with potassium ferrocyanide. The reaction proceeded smoothly at 100 or 120?oC with K2CO3 or KOAc as base, delivering a variety of aromatic nitriles in good to excellent yields. The isolation of the crude products is facilely performed by extraction with cyclohexane and more importantly, both expensive Pd(OAc)2 and XPhos–SO3Na in PEG-400/H2O system could be easily recycled and reused at least six times without any apparent loss of catalytic efficiency. Graphical Abstract: Palladium-catalyzed cyanation of aryl chlorides with potassium ferrocyanide leading to aryl nitriles by using Pd(OAc)2/XPhos–SO3Na/PEG-400/H2O as a highly efficient and recyclable catalytic system is described.[Figure not available: see fulltext.]
