RESUMO
Recent work by Wasserscheid, et al. suggests that PPh4 + is an organic molecular ion of truly exceptional thermal stability. Herein we provide data that cements that conclusion: specifically, we show that aliphatic moieties of modified PPh4 +-based cations incorporating methyl, methylene, or methine C-H bonds burn away at high temperatures in the presence of oxygen, forming CO, CO2, and water, leaving behind the parent ion PPh4 +. The latter then undergoes no further reaction, at least below 425 °C.
