摘要：
Blame it on the alcohol: Kinetic studies, in combination with theoretical calculations, support a mechanism in which the coordination of one alcohol molecule activates a TiIV pre-catalyst (see scheme). The alcohol coordination has a twofold action: it switches the TiVI peroxo complex to an active geometry, and it stabilises the reactive peroxo intermediate through hydrogen bonding.
