Participants

Reaction Steps

2.71 g of the above (2d) (3.73 mmol) and 15 mL of a 10 wt % Pd/C ethyl acetate solution (0.0150 g) were mixed, and stirred for 2 days in a hydrogen atmosphere at room temperature. The solution was filtrated by Celite, and then concentrated to obtain a colorless oily material of 1,7-bis(4-aminophenoxyhexyl)-1,1,3,3,5,5,7,7-octamethyltetrasiloxane (3d) (2.47 g, 99% of yield) represented by the following formula. Various measurements were carried out with regard to the obtained (3d), and results are shown below.
