Alcohols were acetylated or formylated with triphenylphosphine and carbon tetrabromide in ethylacetate or ethyl (or methyl) formate at room temperature. THP or TBDMS ether of primary alcohol got converted into formate or acetate under the experimental conditions employed in one pot operation.

of polymer materials typically requires different wavelengths or additional heat to induce reversible covalent bond formation and dissociation. Here, we bypass the use of invasive triggers by introducing light-stabilised dynamicmaterials that can undergo a repeatable change in topology from a covalently crosslinked material into a liquid polymer formulation by switching one visiblelight source on-and
This invention relates to a range of alpha substituted 2-benzyl substituted imidazole compounds and pharmaceutically acceptable salts and solvates thereof, to compositions comprising such compounds, processes for their synthesis and their use as parasiticides.
