1-Trimethylsilyloxy-3-butyne is an organosilicon compound characterized by the presence of a trimethylsilyloxy group attached to a butyne structure. This compound typically exhibits a linear alkyne configuration, which contributes to its reactivity, particularly in nucleophilic addition reactions. The trimethylsilyloxy group enhances the stability of the molecule and can influence its solubility in organic solvents. It is often used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and in the preparation of more complex molecules. The presence of the silyloxy group can also provide protection for reactive functional groups during synthetic transformations. In terms of physical properties, it is generally a colorless liquid or solid, depending on the specific conditions, and it may have a characteristic odor. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested, and appropriate personal protective equipment should be used.

1-Trimethylsilyloxy-3-butyne

1-Trimethylsilyloxy-3-butyne is a terminal alkyne with one trimethylsilyl group on the terminal carbon. It is used as a solvent for catalytic reactions, especially in cross-coupling reactions. 1-Trimethylsilyloxy-3-butyne can be used to synthesize disubstituted alkenes from unactivated alkenes and iodides or copper. The reaction proceeds efficiently at room temperature in the presence of a phosphine and an organic base. The use of 1-trimethylsilyloxy-3-bulyne eliminates the need for molecular oxygen and makes it possible to carry out aerobic reactions without the use of expensive metal catalysts.
