Electron Transfer Reactions in Pulping Systems (VI): Alcohol Bisulfite Pulping

摘要

Compound 1, which incorporates a hex-5-enyl group on a quinone methide precursor, has been used to demonstrate that NaHSO3 in 50 isopropyl alcohol exhibits electron transfer reactions. There is a signifi- cant solvent effect associated with this system since NaHSO3in aq. NaOH showed very few products typical of an electron transfer system, while 50 isopropyl alcohol by itself at 150#xB0;C provided some of the typical products. The electron transfer ability of the 50 isopropyl alcohol/NaHSO3system increases with increasing temperature but is less than that of aqueous anthrahydroquinone at similar temperatures.
