Versuchsvorschrift
In a manner analogous to that described in Example 1, 16 g of triisobutylaluminum and 13.72 g of 2-phenyl-phenol are reacted in absolute toluene to afford (2-biphenylyloxy)diisobutylaluminum and this is then reacted with 20.52 g of pyridine-N-oxide-2-thiol to yield the title compound. The isolation of the product is carried out in an analogous manner. The yield of (2-biphenylyloxy)bis(2-pyridinethiolato)aluminum N,N'-dioxide, an almost white powder, is 33.4 g, about 92.5% of theory. Upon heating it sinters from about 174° C. and melts at 236°-238° C.
