N-heterocyclic carbenes (NHCs) have emerged as a unique molecular platform for the formation of self-assembled monolayers (SAMs) on various surfaces. However, active carbene formation requires deprotonation of imidazolium salt precursors, which is mostly facilitated by exposure of the salt to

Simple and cheap alcohols can promote the direct arylation of unactivated arenes with aryl iodides and bromides in the presence of potassium tert-butoxide. This transition-metal-free aromatic C-H transformation offers a cheap and easy practical way to synthesize biaryls under mild

The usefulness of the potassium tert-butoxide/dimethyl sulphoxide/ethyl iodide reaction with carbamate and phenylurea herbicides, and its application to phenoxy acids as a way to prevent hazards and toxicity of the sodium hydride/dimethyl sulphoxide/methyl iodide reaction was studied. Using factorial design
