Usage

Chemical Properties

White, odorless powder. Decomposes violently on heating or contamination. Insoluble in water; soluble in organic solvents.

Uses

Curing agent for silicone rubbers.

Definition

A mixture of 50% bis(p-chlorobenzoyl)peroxide in silicone fluid.

General Description

Odorless white solid or paste. Sinks in water.

Reactivity Profile

In pure crystalline form there is danger of explosion upon heating, shock, or friction. Peroxides are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion.

Hazard

Dangerous fire and explosion risk, explodes when heated to 38C, strong oxidizer, will ignite on contact with organic materials. Store in dark, cool locality. Toxic.

Safety Profile

Moderately toxic byintraperitoneal route. Probably an irritant to skin andmucous membranes. Dangerous fire hazard; a powerfuloxidizer. Store in a cool place away from fire hazards,sparks, open flames, and out of the direct rays of the sun.Dangerous e

Carcinogenicity

The only other data available for this organic peroxide show that it had no effects on tumor cells when injected intraperitoneally at 125mg/kg in the chest wall of mice .

Aryl acyl peroxides for visible-light induced decarboxylative arylation of quinoxalin-2(1: H)-ones under additive-, metal catalyst-, and external photosensitizer-free and ambient conditions

Aryl radicals were generated for the first time from cheap and easily available aryl acyl peroxides in eco-friendly ethyl acetate under ambient conditions and visible-light illumination in the absence of any additive, metal catalyst, or external photosensitizer. The present arylation of quinoxalin-2(1H)-ones was chemo- and regioselective, and provided good access to various 3-arylquinoxalin-2(1H)-ones. This journal is

An unprecedented cobalt-catalyzed selective aroylation of primary amines with aroyl peroxides

A novel and facile cobalt-catalyzed selective aroylation of primary amines with aroyl peroxides was developed for the synthesis of aryl amides. It was unprecedented that C[sbnd]N bond formation product was selectively generated without the common N[sbnd]O bond formation product. Aroyl peroxides act as the sole aroylation reagent without additional base or oxidant. The reactions proceeded under mild conditions and showed broad substrates scope with a series of primary amines and aroyl peroxides.

Thermoinduced Free-Radical C-H Acyloxylation of Tertiary Enaminones: Catalyst-Free Synthesis of Acyloxyl Chromones and Enaminones

In this paper, the direct acyloxylation of the α-C(sp2)-H bond in tertiary β-enaminones is accomplished under catalyst-free conditions and ambient temperature by using aroyl peroxides as coupling partners. By means of a thermoinduced free-radical pathway, the present method enables facile and efficient synthesis of both acyloxylated chromones and enaminones.
