Tripropylsilane is a chemical compound from the group of organosilicon compounds .

Extraction and presentation

Tripropylsilane was first produced in 1881 by C. Pape by reacting trichlorosilane with dipropylzinc at 150 ° C in a sealed glass tube.

${\displaystyle {\ce {2HSiCl3{}+3Zn(CH2CH2CH3)2->[\mathrm {150~{}^{\circ }C} ]2HSi(CH2CH2CH3)3{}+3ZnCl2}}}$
