23523-33-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23523-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,2 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 23523-33:
(7*2)+(6*3)+(5*5)+(4*2)+(3*3)+(2*3)+(1*3)=83
83 % 10 = 3
So 23523-33-3 is a valid CAS Registry Number.

Preparation method of bis(triphenyl phosphine)palladium bromide

-

Paragraph 0019-0033, (2019/10/23)

The invention discloses a preparation method of bis(triphenyl phosphine)palladium bromide. The preparation method comprises following steps: 1, palladium bromide is dissolved with a hydrochloric acidsolution, and sodium bromide is added for stirring react

supporting information, p. 15683 - 15687 (2017/11/16)

Reported herein is a novel visible-light photoredox system with Pd(PPh3)4 as the sole catalyst for the realization of the first direct cross-coupling of C(sp3)?H bonds in N-aryl tetrahydroisoquinolines with unactivated alkyl bromides. Moreover, intra- and intermolecular alkylations of heteroarenes were also developed under mild reaction conditions. A variety of tertiary, secondary, and primary alkyl bromides undergo reaction to generate C(sp3)?C(sp3) and C(sp2)?C(sp3) bonds in moderate to excellent yields. These redox-neutral reactions feature broad substrate scope (>60 examples), good functional-group tolerance, and facile generation of quaternary centers. Mechanistic studies indicate that the simple palladium complex acts as the visible-light photocatalyst and radicals are involved in the process.

Improved synthesis method of palladium complex

-

Paragraph 0006, (2017/06/02)

The invention discloses an improved synthesis method of a palladium complex (X in a general formula is equal to Br or I) and belongs to the field of organic chemistry. The improved synthesis method is characterized by including: using PdCl2(PPh3)2 and sodium iodide or sodium bromide as raw materials, wherein a feeding molar ratio is 1:10; using dichloromethane and water as solvents according to a volume ratio of 1:1, reacting to obtain a product, and subjecting the product to extracting, washing and filtering to obtain high-quality PdX2(PPh3) palladium complex. The palladium complex is high in yield, the method is simpler, the raw materials are cheaper, and the method has good industrial application prospect.
