Abstract

Fused phenylcycloalkyl derivatives Q 1040Formation of Titanacyclobutenes with a Spiro-Bonded Cyclopropane. -A versatile procedure for the synthesis of alkenylcyclopropanes via air-and moisture-stable titanacyclobutenes is described. The structure of intermediates of type (IV) with a spiro-bonded cyclopropane ring is documented. -(SHONO, T.; NAGASAWA, T.; TSUBOUCHI, A.; NOGUCHI, K.; TAKEDA*, T.; Chem.
