Synthesis and characterisation of the unsubstituted dipyrrin and 4,4-dichloro-4-bora-3a,4a-diaza-s-indacene: improved synthesis and functionalisation of the simplest BODIPY framework
(2013)
An improved and scalable synthesis of the unsubstituted
4,4-difluoro-4-bora-3a,4a-diaza-s-indacene framework facilitates access to the previously unreported
parent dipyrrin HCl salt, as well as 4,4-dichloro-4-bora-3a,4a- ...
Cl-BODIPYs: a BODIPY class enabling facile beta-substitution
(2012-01)
Cl-BODIPYs, synthesized in high yields from dipyrrins under air- and moisture-free conditions,
are extremely facile to substitution at boron compared to their corresponding F-BODIPYs, opening up
a new route to BODIPYs ...
Investigations into the nucleophilic meso-substitution of F-BODIPYs and improvements to the synthesis of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene.
(2011)
A series of three F-BODIPYs, with varying levels of steric crowding about the meso-position were
selected to investigate nucleophilic meso-substitution of F-BODIPYs. The synthesis of one of these
F-BODIPYs, 4,4-difluor ...
The first series of alkali dipyrrinato complexes
(2010-08)
The first series of alkali dipyrrinato complexes is reported, encompassing lithium, sodium, and
potassium salts of meso-unsubstituted and meso-aryl-substituted derivatives. By varying the
substituents at the meso position, ...
An Improved Method for the Synthesis of F-BODIPYs from Dipyrrins and Bis(dipyrrin)s
(Organic Letters, 2012)
An improved methodology for the synthesis of F-BODIPYs from dipyrrins and bis(dipyrrin)s is reported. This strategy employs lithium salts of dipyrrins as intermediates that are then treated with only one equivalent of boron ...
Use of F-BODIPYs as a protection strategy for dipyrrins: optimization of BF2 removal.
(Journal of Organic Chemistry, 2012)
We recently reported the first general method for the deprotection of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes (F-BODIPYs) involving a microwave-assisted procedure for the removal of the BF2 moiety, and liberation of ...
