Tropones, Tropolones, and Tropylium Salts with Fused Heterocyclic Rings Part I Synthesis ... 

The synthesis of tropones, tropolones, and tropylium salts with fused heterocyclic rings forms the first part of a projected two-chapter sequence by G. Fischer (Leipzig, Germany). It is planned that the structure, reactivity, and applications of these compounds will be discussed in a further contribution in a subsequent volume.
