 Title    Cyclobutadien-homologe Diazadiboretidine als Liganden von Übergangsmetallen Cyclobutadiene-Homologous Diazadiboretidines as Ligands to Transition Metals  
 Abstract    The sandwich type product CpCoL (lc) and the carbonyl species (OC^FeL (2c), (OC) 4 CrL (3e), (OC) 4 MOL (4b), and (OC) 4 WL (5b) were prepared with diazadiboretidines (RBNR') : (L) as tetra-hapto ligands (a—d: R = Me, Et, Pr. Bu; R' = /Bu; e: R = R' = /Pr). The ligand (/PrBN/Pr) 2 , prepared by a novel catalytic cyclodimerisation of /PrB=N/Pr, undergoes subse-quent cyclodimerisation to the eight-membered ring (/PrBN/'Pr) 4 at ambient temperature, where-as the corresponding cycloreversion occurs at 100 °C. The structure of the complexes (OC) x ML is discussed by means of IR and NMR data and the structures of crystalline 2c and 5d were determined by X-ray crystallography.
