N2 - Some new 3,4,5-substituted isoxazoles, 3,4,5 and 1,3,4,5-substituted pyrazoles were prepared by reaction of,-oxoketen dithioacetals with hydroxylamine hydrochloride; phenyl hydrazine and hydrazine hydrate respectively under solvothermal conditions involving an ecofriendly method without any environmental pollution. The yields are in the range of 71-91%. The structure of the new compounds were established upon their elemental analysis, IR, 1H NMR, and 13C NMR.
