Hetarenes IV (Six And Higher-membered Ring Systems With Two Or More Heteroatoms)

Covers the chemistry of six-membered hetarenes, with two or more heteroatoms (oxygen, sulfur, nitrogen) which are treated in the order as given by the IUPAC priority rules. However, compounds with an annulated (hetero)-aromatic ring are covered following, in each case, the parent monocycle.
