Usage

General Description

1-butyl-3-(4-chlorophenyl)urea, also known as "diuron," is a white crystalline solid that is widely used as an herbicide to control weeds in various crops and non-crop areas. It works by inhibiting photosynthesis in plants, preventing their growth and reproduction. Diuron is considered a non-selective herbicide, meaning it can affect a wide range of plant species. It is also persistent in the environment, with a long half-life in soil and potential for leaching into water sources. Due to its potential environmental and human health risks, diuron is regulated and its use is restricted in some jurisdictions. It is important for users to follow safety guidelines and regulations when handling and applying this chemical.

Lanthanum(III) Trifluoromethanesulfonate Catalyzed Direct Synthesis of Ureas from N-Benzyloxycarbonyl-, N -Allyloxycarbonyl-, and N -2,2,2-Trichloroethoxycarbonyl-Protected Amines

A novel lanthanum triflate mediated conversion of N -benzyloxycarbonyl-, N -allyloxycarbonyl-, and N -trichloroethoxycarbonyl-protected amines into nonsymmetric ureas was discovered. In this study, lanthanum triflate was found to be an effective catalyst for preparing various nonsymmetric ureas from protected amines. A variety of protected aromatic and aliphatic carbamates reacted readily with various amines in the presence of lanthanum triflate to generate the desired ureas in high yields. This result demonstrated that this novel lanthanum triflate catalyzed preparation of ureas from Cbz, Alloc, and Troc carbamates can be employed for the formation of various urea structures.
