eng	Substituted diiminoisoindoles and their metallacyclic compounds: structures and synthesis	Isoindole derivatives play an important role in many fields of chemistry. The isoindole fragment can be found in resistant pigments such as phthalocyanines1, pharmaceuticals but also in nature as a part of alkaloids2. Series of isoindole-based ligands were prepared with goal to investigate potential of these systems also in coordination and organometallic chemistry. Variating substituents on the diiminoisoindole backbone allowed us to prepare a wide range of ligands with diverse properties. Potential in coordination chemistry was examined trough reactions with alkali and alkaline earth metals and also organozinc and organoaluminium compounds. Interesting reactivity was disclosed in cases of diiminoisoindoles substituted by acyl halides (Fig. 1 A, C). These ligands possess carbonyl group, which allows them to form six-member metallacycles. Similar triazametallacyclohexane rings are formed also by guanidinate-substituted diiminoisoindoles. In this case, however, the guanidinate nitrogen is involved in the coordination (Fig. 1 B). Despite the fact that diiminoisoindoles are better known in form of macrocyclic compounds, this work shows they can offer wide range of binding modes and interesting compounds even in their acyclic form.
