2-(3-Butenyloxy)-4,4'-dinitrobiphenyl → 4,4'-Dinitro-1,1'-biphenyl

Participants

Reaction Steps

2.52 g of the 2-(3-butenyloxy)-4,4'-dinitrobiphenyl synthesized in Reference Example 1 was dissolved in 80 mL of dry toluene. To this was first added 100 microliters of a 3% chloroplatinic acid 2-propanol solution, and a solution in 20 mL dry toluene of 7.88 g of hydrogen-terminated polysiloxane (average value of n: 14.4) with the formula ##STR17## was then added dropwise. Heating was continued for 4 hours at 100° C. Purification by column chromatography yielded 8.68 g of the 4,4'-dinitrobiphenyl-terminated polysiloxane as a waxy light yellow solid.
