Reaction Conditions:
with tetrabutyl ammonium fluoride in tetrahydrofuran at 60; for 2.5 h;Inert atmosphere;Sealed tube;
Steps:
44.1 Formation of tributyl(prop-1-yn-1-yl)stannane
Under argon protection,To a dry sealed closed pot was filledTrimethyl (prop-1-ynyl) silane (2.00 g, 17.82 mmol), 1,1,1,3,3,3- hexabutyl-distannoxane(5.26 g, 8.82 mmol) and 40mL tetrahydrofuran.People in power Tetrabutyl ammonium stannous (360 mL, 360.00 mmol, dissolved in tetrahydrofuran, the concentration of 1 mol / L), the mixture was stirred in the sealed and closed pot at 60 ° C for 2.5 hours. After removal of the volatile material was tributyl (1-ynyl) stannane (3.5 g, crude) as a colorless oil, was used directly without further purification in the next step.
