SYNTHESIS AND CONVERSIONS OF METALLOCYCLES .12. C-13 NMR-SPECTRA OF TRICYCLIC AND TETRACYCLIC ORGANOALUMINUM COMPOUNDS WITH A BRIDGE STRUCTURE

The C-13 NMR spectra of a new class of tri- and tetracyclic organoalum inum and organosulfur bridge-type compounds, containing five-membered heterocycles with an exo-orientation, are discussed. The assignment of the signals and determination of the isomerism of the compounds studi ed were performed using the spectra of their hydrocarbon analogs, addi tive calculations, and an analysis of the spectra of products of deute ration and hydrolysis of organoaluminum compounds.
