The synthesis of the fully fluorinated bis-anilido ligand N , N ′-bis-pentafluorophenyl-3,4,5,6-tetrafluorophenylene-1,2-diamine, 1 is described. Reaction of one or two equivalents of 1 with AlMe 3 gives aluminium compounds incorporating one or two ligands, the latter being the protonated form of a...

| Summary: | The synthesis of the fully fluorinated bis-anilido ligand
N
,
N
′-bis-pentafluorophenyl-3,4,5,6-tetrafluorophenylene-1,2-diamine,
1
is described. Reaction of one or two equivalents of
1
with AlMe
3
gives aluminium compounds incorporating one or two ligands, the latter being the protonated form of a new weakly coordinating anion (WCA),
3
-H
. Alternatively, reaction of
1
with LiAlH
4
yields the lithium salt of this anion,
3
-Li
, which may be employed as a reagent for preparing the trityl and
N
,
N
-dimethylanilinium salts of the aluminate anion. All ion pairs are fully characterized and the use of
3
-Ph
3
C
to generate titanium-based alkyl cations is also described.
A new perfluoroamido aluminate weakly coordinating anion is described, along with useful reagents for its use in activating olefin polymerization catalysts. |
