A nickel-catalyzed cross-coupling reaction between aryltitanium(IV) alkoxides and various functionalized aryl halides is described. The reaction requires Ni(acac) 2 (0.5 mol%), a phosphine or an N-heterocyclic carbene ligand (NHC ligand; 0.5-1.0 mol%) and proceeds at 25 °C within 1-24 hours.

The present invention relates to novel biphenyl compounds of the formula ##STR1## wherein one of R.sup.1 and R.sup.2 is hydrogen and the other is --CH.sub.3-m X.sub.m wherein X is chloro or bromo and m is an integer one or two, and the cyclic moiety A is a -2,5-; -2,3-; or -3,4-di-OR-1-phenyl moiety wherein R is a hydroxy-protecting group and to a method of preparing same. The biphenyl compounds are useful as intermediates in preparing redox compounds containing a phenylhydroquinone or phenylcatechol moiety.
Disclosed are compounds and derivatives thereof their synthesis, and their use as Rho-kinase inhibitors. These compounds of the present invention are useful for inhibiting tumor growth, treating erectile dysfunction, and treating other indications mediated by Rho-kinase, e.g., coronary heart disease.
