A technique is described for the preparation of a wide variety of basic derivatives of linearly condensed tricyclic systems formed by two external benzene nuclei and a 7-membered central ring having 2 chalcogen atoms as hetero atoms. Derivatives of 11H-dibenzo(b,e)-1,4-dioxepin are obtained when the chalcogens are both oxygen atoms; derivatives of 11H-dibenzo(b,f)-1,4-dithiepin are obtained when the chalcogens are both sulfur atoms; derivatives of 6H-dibenz(b,e)-1,4-oxathiepin and 11H-dibenz(b,f)-1,4-oxathiepin are obtained with combinations of sulfur and oxygen atoms as chalcogens.
