The effect of solubility on the stability of titanium(IV) arene complexes derived from hexasubstituted arenes and TiCl4

The investigation of new titaniuni(IV) hexaalkylarene complexes gave new insight into the stability of high-valent metal arene complexes. In contrast to low-valent transition metal arene complexes these complexes are in equilibrium with the free arenes. The stability of the complexes was shown to depend strongly on both the donor ability of the arene and on their solubility. This is unprecedented in transition metal arene chemistry.

On the Mechanism of the Singulet Excited Photo-Isomerization of the Homofulvene System

Syntheses of the four at the cyclopropane part alkyl-substituted homofulvenes 6-endo-Ethyl-1,2,3,5-tetramethyl-4-methylenebicyclohex-2-ene (endo-1a), 6-exo-Ethyl-1,2,3,5-tetramethyl-4-methylenebicyclohex-2-ene (exo-1a), 6-endo-Isopropyl-1,2,3,5-tetramethyl-4-methylenebicyclohex-2-ene (endo-1b) and 6-exo-Isopropyl-1,2,3,5-tetramethyl-4-methylenebicyclohex-2-ene (exo-1b) are reported.Following singulet excitation endo-1a, endo-1b and exo-1b underwent photo-isomerization to 6-Ethyl-1,2,3,4-tetramethyl-5-methylenecyclohexa-1,3-diene (2a) and 6-Isopropyl-1,2,3,4-tetramethyl-5-methylenecyclohexa-1,3-diene (2b) resp.It is demonstrated, that C-6 - the top of the cyclopropane ring in 1 - is transferred to C-6 - adjacent to the exo-methylene substituent - in the 5-methylenecyclohexa-1,3-diene system 2.A mechanism is suggested. - Keywords: Homofulvene System, Photo-Isomerization, Mechanism
