A novel O–H bond activation reaction is reported: thermal SO2.+ radical cations activate the O–H bond of water in the gas phase exclusively producing SO2H+ and OH radicals. This water activation is among the fastest OH.-forming reactions that occur with charged electrophiles in the gas phase, with 100% efficiency. The atmospheric relevance of the process are evaluated, for instance in those environments where ions reach high local concentrations, such as wet air ionized by coronas along high-voltage power lines.

Abstract
A novel O–H bond activation reaction is reported: thermal SO2.+ radical cations activate the O–H bond of water in the gas phase exclusively producing SO2H+ and OH radicals. This water activation is among the fastest OH.-forming reactions that occur with charged electrophiles in the gas phase, with 100% efficiency. The atmospheric relevance of the process are evaluated, for instance in those environments where ions reach high local concentrations, such as wet air ionized by coronas along high-voltage power lines.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
