A general method for the Pd-catalyzed coupling of methanol with (hetero)aryl halides is described. The reactions proceed under mildconditions with a wide range of aryl and heteroaryl halides to give methyl aryl ethers in high yield.

The synthesis of dihydrobenzo[1,4]oxazines has been accomplished efficiently by copper catalyzed intramolecular cyclization of the adducts formed by the treatment of 1,2-cyclic sulfamidates with 2-halo phenols. The products (except two) are new and their yields are high. The catalyst is easily available and less expensive.
