• Desireable metal containing cyclomatic compounds are those with cyclic rings having high burning velocities. The higher the burning the velocity, generally the higher the preference. Generally larger rings have higher burning velocities compared to smaller rings. Thus, a cyclooctane ring is preferred over cyclohexane, which is perferred over a cyclobutane ring. Saturated rings are normally more perferred over unsaturated rings. The more saturated the ring the more preferred. Thus, cyclohexane is preferred over benzene. Ring systems where the metal is in turn attached to one or more a hydroxyl, carbonyl, an alkyloxy radicals is preferred.
• Non-limiting examples of desireable ring systems/complexes include: cyclohexane, cyclohexene, cyclopentane, cyclobutane, cyclopentadiene, phenyl, benzene, and naphthalene.
