22332-89-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22332-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,3 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22332-89:
(7*2)+(6*2)+(5*3)+(4*3)+(3*2)+(2*8)+(1*9)=84
84 % 10 = 4
So 22332-89-4 is a valid CAS Registry Number.

PROCESS FOR THE PREPARATION OF ORGANIC BROMIDES

-

Paragraph 00169; 00180; 00185, (2017/07/28)

The present invention provides a process for the preparation of organic bromides, by a radical bromodecarboxylation of carboxylic acids with a bromoisocyanurate.

Facile conversion of aldehydes and ketones to gem-dichlorides using chlorodiphenylphosphine/N-chlorosuccinimide as a new and neutral system

Aghapour, Ghasem,Afzali, Asieh

experimental part, p. 4023 - 4035 (2009/04/11)

Aldehydes and ketones are easily converted to their corresponding gem-dichlorides using a mixture of chlorodiphenylphosphine and N-chlorosuccinimide (ClPPh2/NCS) in dichloromethane under neutral conditions and at room temperature. Copyright Taylor & Francis Group, LLC.

MECHANISMS OF FREE-RADICAL REACTIONS. XX. REACTIVITY IN THE FREE-RADICAL HALOGENATION REACTIONS OF ARYLFLUOROALKANES

Dneprovskii, A. S.,Eliseenkov, E. V.

, p. 711 - 719 (2007/10/02)

The free-radical chlorination and bromination of meta- and para-substituted benzyl fluorides and 1,1-difluoro-2-phenylethane and also the chlorination of 1-fluoro-2-arylethanes by phenylchloroiodonium chloride and the bromination of meta- and para-substituted benzyl bromides were studied by the method of competing reactions.In all cases a good correlation is observed between log krel and the Brown ?+ constants.In cases where change in the reactivity in the transition from one reaction series to another is due mainly to the polar effect of the substituent whilethe selectivity is measured in relation to the polar effect direct relationships are observed between the reactivity and the selectivity.
