実験手順
In step a, trimethylsilylacetylene (1) can first be reacted with a non-nucleophilic base, such as lithium hexamethyldisilazane, in a suitable aprotic solvent, such as tetrahydrofuran. The resulting lithium acetylide can then be reacted with the appropriate benzaldehyde compound of structure 2 to give the corresponding α-[(trimethylsilyl)ethynyl]-benzenemethanol compound of structure 3.
