Expanding available pyrazole substitution patterns by sydnone cycloaddition reactions

We report the use of alkynylsilanes for the regiocontrolled synthesis of pyrazoles from functionalised sydnones. The strategies outlined herein allow a range of pyrazoles to be accessed with substitution patterns that are otherwise not directly obtained with high selectivity by alkyne cycloadditions. Moreover, this study serendipitously highlighted a simple and convenient procedure for the synthesis of aryl monofluoromethyl ethers through the combination of TBAF and dichloromethane.

The kinetics of reaction between methylene iodide and phenoxide ion have been studied in 50 percent (v/v) aq.DMSO, aq.DMF and aq. acetone.The activation parameters for the reaction have been determined in aq.DMSO.The reactivity pattern has been rationalized in the light of Hammett's linear free energy relationship.The reaction essentially involves attack on the oxygen atom of phenoxide ion.The validity of the isokinetic relationship has been examined using Exner's method.
