Abstract
![]()
A new method employing
iron(III) acetylacetonate along with visible
light is described to effect oxidative ring opening of cyclic ethers
and acetals with unparalleled efficiency. The method allows for a
photocatalytic radical chemistry approach to functionalize relatively
inert cyclic ethers into useful synthetic intermediates. The methodology
sheds further light on the use of underexplored iron complexes in
visible-light photochemical contexts and illustrates that simple Fe(III)
complexes can initiate redox processes from 4LMCT excited
states.

Abstract
Aromatic acetals have been deprotected to the corresponding aldehydes under biomimetic conditions for the first time using beta-cyclodextrin in water under neutral conditions, thereby overcoming many of the drawbacks associated with earlier methodologies. This method, apart from being simple with regard to recycling of the catalyst, also has the potential for industrial applications.
