Usage

General Description

N,N-diphenylbenzohydrazide, also known as diphenylbenzohydrazide (DPB), is a chemical compound used as a UV stabilizer in plastics and polymers. It functions by absorbing ultraviolet radiation and preventing it from degrading the material. DPB is also used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is considered to be relatively safe and stable under normal handling and storage conditions, with a low risk of toxicity and environmental impact. However, proper safety precautions should still be followed when handling and working with this chemical. Overall, N,N-diphenylbenzohydrazide is a versatile and important chemical in various industries due to its UV stabilizing and synthetic properties.

Copper(ii)-catalyzed coupling reaction: An efficient and regioselective approach to N′,N′-diaryl acylhydrazines

Using N′-aryl acylhydrazines as aryl donors, a novel copper(ii)-catalyzed homo-coupling reaction of N′-aryl acylhydrazines has been developed for the synthesis of N′,N′-diaryl acylhydrazines. We also provided a complementary procedure for the preparation of unsymmetrical diaryl acylhydrazines via cross-coupling reaction. These protocols featured mild reaction conditions, wide functional group tolerance and highly regioselective products. Control experiments indicated that this kind of coupling reaction might undergo a transient acyl diazene intermediate. This journal is

An oxidative transformation of N′-phenylhydrazide to t-butyl ester using a copper(II) halide-lithium t-butoxide system

Reactions of hydrazides or N1-phenylhydrazides with a copper(II) reagent prepared from copper(II) bromide and lithium t-butoxide smoothly proceeded to give the corresponding t-butyl ester in high yield.
