The reactions of 2,3-dihydro-2,2,2-triphenylphenanthro[9,10-d]-1,3,2-λ5-oxazaphospholes with aromatic aldehydes lead to the corresponding 2-substituted phenanthro[9,10-d][1,3]oxazoles via an aza-Wittig reaction in good yields.
1,4-Benzoxazin-2-ones, benzo[d]oxazoles and 2H-1,4-benzoxazines from the reaction of 2-(methoxyimino)benzen-1-ones with arylacetates, arylacetic acids and trans-stilbene

10-(Methoxyimino)phenanthrene-9-one 1 reacts thermally with the arylacetic derivatives 2(a-j) to yield the corresponding 1,4-benzoxazin-2-ones 4(a-d,f) and benzo[d]oxazoles 5(a-e,g). Similarly, reaction of the monoximes 7a, 7b with compounds 2a, 2d respectively affords 8a, 8b, while action of trans-stilbene on the monoximes 1, 7a, 7b leads to the 1,4-benzoxazines 10, 11, 13, obtained along with the corresponding 2-phenyloxazoles 5a, 8a, 8c and compound 12.

Certain 2-aryl derivatives of phenanthrazole have been synthsized and their spectral and luminescence properties have been investigated.It has been shown that the introduction of acceptor substituents into the para position of the 2-phenyl radical c
