T1  - Structure and dynamics of free and metallated benzonaphthopyranones and -pyrans
N2  - First calculations of the structures of metal-free and complexed biaryl lactones and their confrrmation by X-ray crystaIlography, the search for the transition states of their heIimerization processes, and the spectroscopic determination of the heIimerization barriers of related cyclic ethers by DNMR are reported.
