Abstract

The chloro and azido complexes trans-[PdCl (4-C5NF4)(PiPr3) 2](3) and trans-[Pd (N3)(4- C5NF4)(PiPr3) 2](4) can be prepared by reaction of [PdF (4-C5NF4)(PiPr3) 2](2) with Et3SiCl or MeSiN3, respectively. In contrast, reactions of 2 with Ph3SiH or Me2FSiSiFMe2 give the products of reductive elimination 2, 3, 5, 6-tetrafluoropyridine (5) or 4- (fluorodimethylsilyl) tetrafluoropyridine (6) as well as [Pd (PiPr3) 2](1). In a catalytic ...
