ABSTRACT:

10,1o-Dimethyl-9,10-dihydro-10-sila-2-azaantron I was prepared from 110,10-dimethyl-9,10-dihydro-10-sila-2-azaanthracene by the oxidation of mrthlene group at position-9. 9-Oxy-9 phenylethynyl-1,10,10-dimethyl-9,10-dihydro-10-sila-2-azaanthracene II was later obtained by reacting dihydrosiliaazaantron I with phenylacetylene and methyl iodide. Mayer-Suster rearrangement reaction was later carried out In presence of H2S04 which gave two isomeric products III with 1:1 ratio. Later the vinyl ketones III were converted into oximes IV with hydroxylamine hydrochloride in pyridine.
