Silylation of N-(2-hydroxyphenyl)acetamide by methyl(organyl)dichlorosilanes: Structure and properties of resulting heterocycles

Add time:07/24/2019    Source:sciencedirect.com

The interaction of N-(2-hydroxyphenyl)acetamide with methyl(organyl)dichlorosilanes RMeSiCl2 (R = Me, Vinyl, Ph) leads to the formation of 5-membered silaheterocyclic benzoxazasiloles 1a-3a. According to data of NMR and FTIR spectra these compounds exist in equilibrium with 7-membered cyclic benzodioxazasilepines 1b-3b which have the imidate structure. The structure of compound 1a was proved by X-ray analysis. Compounds 1a-3a are hydrolyzed to form silanols 4–6. 3-Acetyl-2,2-dimethyl-2,3-dihydro-1,3,2-benzoxazasilole 1a reacts with methanol and isopropanol and transforms into silanes 7 and 8.
