Abstract Substitution of only one bridged hydrogen atom of bis(1,2-cycloheptanedionedioximato)nickel(II) by the diphenylboron group is easily accomplished with formation of1. Both hydroxy groups of bis(dihydroxyboron-diaminoglyoximato)nickel(II) chelate2 can be esterified by phenol or methanol (chelates2 a andb). The bis(diphenylboron) chelate3 a results from the reaction of bis(dihydroxyborondiaminoglyoximato)nickel(II) with diphenylboric anhydride. In the same way the corresponding chelates3 b-f are obtainable from the boron-free nickel chelates. The i.r. and u.v. spectra as well as the diamagnetic character of the compounds described are in agreement with planar structures.
