Reactions of ruthenium(II) tris(pyrazolyl)borate and tris(pyrazolyl)methane complexes with diphenylvinylphosphine and 3,4-dimethyl-1-phenylphosphole

Synthesis, structure, and kinetic studies on [RuCl2(NCCH3)2(cod)]

“…In contrast, less attention has been paid to the soluble compound [RuCl 2 (NCCH 3 ) 2 (cod)] despite its potential as an equivalent precursor for ruthenium chemistry due to the lability of the acetonitrile ligands [6][7][8][9][10][11]. In fact, only a handful of compounds have been synthesized from this mononuclear ruthenium (II) complex with the hydridotris(pyrazolyl)borate compound [RuTpCl(cod)] [12], a platform for the synthesis of a range of organometallic compounds [13,14], as the most notable example. Interestingly, compound [RuCl 2 (NCCH 3 ) 2 (cod)] has been recently applied to the synthesis of ruthenium complexes with biological properties and biomedical applications [15][16][17][18][19][20][21].…”

Direct Chlorination of Trispyrazolyl Borate Ligands in Tp-Ruthenium Complexes

“…This could be explained by impeded isomerization of the double bonds in nbd or by stronger metal coordination to the diene. 19 The nbd complex 1b was chlorinated with sulfuryl chloride in THF to give 2b in 81% yield (Scheme 1). The complex 2b was analyzed via X-ray crystallography (Figure 2).…”

“…The shorter distance for the latter confirms that the bonding between ruthenium and nbd was slightly stronger, as has been pointed out previously. 19 Analysis of 2b reveals the disappearance of 1 H NMR peaks for the pyrazole H4 peaks at 6.2 and 6.3 ppm upon chlorination. The 13 C NMR spectrum of 2b showed a peak at 111 ppm from the chlorinated carbon, which was shifted downfield by 5 ppm relative to that peak in 1b.…”

Tris[4-(dimethylamino)pyridine][tris(pyrazol-1-yl)methane]ruthenium(II) bis(hexafluoridophosphate) diethyl ether monosolvate

“…For background to the synthesis, see: Llobet et al (1988); Calvert et al (1983). For examples of other structures of ruthenium complexes of the Tpm ligand, see: Llobet et al (1989); Wilson & Nelson (2003); Katz et al (2005); Iengo et al (2005); Foxon et al (2007); Kuzu et al (2009); Waywell et al (2010); Zagermann et al (2011); De et al (2011); Agarwala et al (2011Agarwala et al ( , 2013; Serrano et al (2011); Cadranel et al (2012). For examples of other structures of ruthenium complexes of the dmap ligand, see: Bonnet et al (2003); Rossi et al (2008Rossi et al ( , 2010; Mutoh et al (2010); Dunbar et al (2011).…”

“…Ruthenium complexes of the tris(1-pyrazolyl)methane (Tpm) ligand have been studied in a number of laboratories, and many examples have been structurally characterized (e.g. Llobet et al, 1989;Wilson & Nelson, 2003;Katz et al, 2005;Iengo et al, 2005;Foxon et al, 2007;Kuzu et al, 2009;Zagermann et al, 2011;De et al, 2011;Agarwala et al, 2011;Serrano et al, 2011;Cadranel et al, 2012;Agarwala et al, 2013). However, the only one featuring three pyridine (py) or pyridyl coligands is the complex salt [Ru II (Tpm)(py) 3 ][PF 6 ] 2 (Laurent et al, 1999), while [Ru II (Tpm)(dppz)(3-NH 2 py)] (Waywell et al, 2010) contains one chelating coligand.…”
