Chlorobenzenes are important starting materials for the preparation of commercially valuable triarylphosphines and tetraarylphosphonium salts, but their use for the direct arylation of elemental phosphorus has been elusive. Here we...
Organophosphorus compounds (OPCs) are highly important chemicals, finding numerous applications in both academia and industry. Herein we describe a simple photocatalytic method for the stannylation of white phosphorus (P4) using...
The divalent iron complexes trans-[FeBr 2 (BINC) 2 ], [Cp*FeCl(BINC)] (Cp* = Me 5 C 5 ), and [FeBr 2 (CNAr 3 NC) 2 ] with the chelating bis(isonitrile) ligands BINC (bis(2-isocyanophenyl)phenylphosphonate) and CNAr 3 NC (2,2″-diisocyano-3,5,3″,5"tetramethyl-1,1′:3′,1″-terphenyl) have been prepared and characterized. Their subsequent reduction yields the di-and trinuclear compounds [Fe 3 (BINC) 6 ], [Cp*Fe(BINC)] 2 , [Fe(CNAr 3 NC) 2 ] 2 , and [K-(Et 2 O)] 2 [Fe(CNAr 3 NC) 2 ] 2 . The molecular structures of all new species were determined by X-ray crystallography and compared to those of related iron carbonyl complexes, demonstrating that the bidentate isonitrile ligands are capable surrogates for two CO ligands with only minimal distortion of the tetrahedral or octahedral geometry of the parent complexes. The complexes were further characterized by NMR and IR spectroscopy, and the electrochemical properties of selected compounds were analyzed by UV−vis−NIR spectroelectrochemistry.
Divalent iron complexes trans-[FeBr2(BINC)2], [Cp*FeCl(BINC)] (Cp* = Me5C5) and [FeBr2(CNAr3NC)2] with chelat-ing bis(isonitrile) ligands BINC (bis(2-isocyanophenyl)phenylphosphonate) and CNAr3NC (2,2’’-diisocyano-3,5,3’’,5’’tetramethyl-1,1’:3’,1’’-terphenyl) have been prepared and characterized. Their subsequent reduction yields di- and trinuclear compounds [Fe3(BINC)6], [Cp*Fe(BINC)]2, [Fe(CNAr3NC)2]2 and [K(Et2O)]2[Fe(CNAr3NC)2]2. The molecular structures of all new species were determined by X-ray crystallography. The molecular structures are compared to related iron carbonyl complexes.
