695-99-8 Usage

Uses

2-Chloro-1,4-benzoquinone may be used in the preparation of chloro derivatives of prenylnaphthohydroquinone.

General Description

2-Chloro-1,4-benzoquinone is a quinone derivative. It is one of the intermediate formed during the degradation of 3,4-dichloroaniline in a dielectric barrier discharge plasma reactor. It is formed during lignin peroxidase catalyzed oxidation of 2-chloro-1,4-dimethoxybenzene. 2-Chloro-1,4-benzoquinone on dechlorination yields 1,2,4-trihydroxybenzene.

Check Digit Verification of cas no

The CAS Registry Mumber 695-99-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 695-99:
(5*6)+(4*9)+(3*5)+(2*9)+(1*9)=108
108 % 10 = 8
So 695-99-8 is a valid CAS Registry Number.

Can Donor Ligands Make Pd(OAc)2a Stronger Oxidant? Access to Elusive Palladium(II) Reduction Potentials and Effects of Ancillary Ligands via Palladium(II)/Hydroquinone Redox Equilibria

Palladium(II)-catalyzed oxidation reactions represent an important class of methods for selective modification and functionalization of organic molecules. This field has benefitted greatly from the discovery of ancillary ligands that expand the scope, reactivity, and selectivity in these reactions; however, ancillary ligands also commonly poison these reactions. The different influences of ligands in these reactions remain poorly understood. For example, over the 60-year history of this field, the PdII/0 redox potentials for catalytically relevant Pd complexes have never been determined. Here, we report the unexpected discovery of (L)PdII(OAc)2-mediated oxidation of hydroquinones, the microscopic reverse of quinone-mediated oxidation of Pd0 commonly employed in PdII-catalyzed oxidation reactions. Analysis of redox equilibria arising from the reaction of (L)Pd(OAc)2 and hydroquinones (L = bathocuproine, 4,5-diazafluoren-9-one), generating reduced (L)Pd species and benzoquinones, provides the basis for determination of (L)PdII(OAc)2 reduction potentials. Experimental results are complemented by density functional theory calculations to show how a series of nitrogen-based ligands modulate the (L)PdII(OAc)2 reduction potential, thereby tuning the ability of PdII to serve as an effective oxidant of organic molecules in catalytic reactions.
