2-Butynyl p-toluenesulfonate

Description:
2-Butynyl p-toluenesulfonate, with the CAS number 56563-37-2, is an organic compound characterized by its sulfonate ester functional group. It features a butynyl group, which is a terminal alkyne, indicating the presence of a triple bond between two carbon atoms. The p-toluenesulfonate moiety contributes to its reactivity, making it a useful intermediate in organic synthesis, particularly in the formation of carbon-carbon bonds. This compound is typically a colorless to pale yellow liquid and is soluble in organic solvents. Its reactivity is influenced by the presence of the sulfonate group, which can facilitate nucleophilic substitutions. 2-Butynyl p-toluenesulfonate is often employed in various chemical reactions, including coupling reactions and as a reagent in the synthesis of more complex organic molecules. Safety precautions should be observed when handling this compound, as it may pose health risks if inhaled or ingested, and appropriate personal protective equipment should be used.
