Participants

Reaction Steps

1,5-bis[4-(4-nitrophenoxy)butyl]-1,1,3,3,5,5-hexamethyltrisiloxane (2.79 g; 4.69 mmol) (2c) and 15 mL of a 10 wt % Pd/C (0.0262 g) ethyl acetate solution was mixed, and stirred for 2 days in a nitrogen atmosphere at room temperature. The solution was filtrated by Celite and then concentrated to obtain a colorless oily material of 1,5-bis[4-(4-aminophenoxy)butyl]-1,1,3,3,5,5-hexamethyltrisiloxane (3b) (2.48 g, 99% of yield) represented by the following formula.
