The reaction of [RuCl2(p-cymene)]2 with benzoxazoleacetonitriles and NH4+BF4 - in methanol leads to bidentate N,N′-benzoxazole-methoxyimine- ruthenium(II) complexes 7, corresponding to the addition of methanol to the ruthenium(II)-activated nitrile triple bond. The X-ray structure of a complex 7 shows equivalent Ru-N and slightly different C=N bond distances. The catalytic hydration of benzoxazolacetonitriles with [RuCl2(p-cymene)] 2 in methanol/water leads to quantitative formation of corresponding amides under mild conditions.
Catalytic asymmetric cyclopropanation of heteroaryldiazoacetates

Rh2(S-DOSP)4-catalyzed decomposition of heteroaryldiazoacetates in the presence of styrene results in highly diastereoselective and enantioselective cyclopropanations. Heteroaryldiazoacetates containing both electron-rich and electron-deficient heterocycles, such as thiophene, furan, pyridine, indole, oxazole, isoxazole, and benzoxazole, are effective in this chemistry. These studies broaden the range of diazo compounds containing both electron-withdrawing and electron-donating groups, which undergo highly diastereoselective cyclopropanations.
