摘要

A series of novel hybrid photoinitiators (YPhCOPhXPhI+PhPF6-

Y = 4-NO2

4-MeO or 3-Cl

X = O

OCH2

or nothing)

which contain multiple aromatic rings (PhCOPhXPh)

were prepared by reaction of easily available aryl ketones (YPhCOPhXPh) with iodosobenzene diacetate [PhI+OCOCH3(CH3CO2)-]. The inset of an aromatic ring into p-benzoyldiphenyliodonium hexafluorophophate (PhCOPhI+PhPF6-) (BDPIH

He-type photoinitiator) between diphenyliodonium and benzoyl is propitious both to the preparation and the photoinitiating activity of ketonic diphenyliodonium photoinitiators. The yield and performance of the novel hybrid photoinitiators are much better than those of the He-type initiator.
