The novel nickel complex, LiAlH/sub 2/(THF)/sub n/ x C/sub 10/H/sub 8/N/sub 2/ x Ni (2), which results from the interaction in a THF solution of (2,2'-bipyridyl)(1,5-cyclooctadiene)nickel (1) with LiAlH/sub 4/ in a 1:1 molar ratio is a powerful desulfurizing agent in homogeneous solution for such aromatic sulfur hetercycles as dibenzothiophene (3), phenoxathiin (11), phenothiazine (12), and thianthrene (13). When employed in a 2:1 molar ratio with the heterocyclic substrate, 2 produces the… Expand
