Platinum Complexes with a Phosphino‐Oxime/Oximate Ligand

“…Thus, we found that, contrary to what happened with 6 , the treatment of a dichloromethane solution of tetramer 9 with a fourfold excess of 1 at room temp. does not lead to the deprotonation of oxime unit of 1 , the reaction yielding the mononuclear derivative fac ‐[PtIMe 3 {κ 2 ‐( P,N )‐2‐Ph 2 PC 6 H 4 CH=NOH}] ( 10 ) which could be isolated in 83 % yield (Scheme ) . Characterization of this complex was straightforward following its analytical and spectroscopic data (see details in the Experimental Section), with key features being as follows: ( i ) ( 31 P{ 1 H} NMR) a singlet resonance at δ P = –0.2 ppm, ( ii ) ( 1 H NMR) characteristic resonances for the hydroxyl and iminic protons of the aldoxime fragment at δ H = 13.05 (broad s) and 8.29 (s, J Pt,H = 19.2 Hz), respectively, as well as three high‐field singlets for the Pt‐coordinated methyl groups ( δ H = 1.06, 1.33 and 1.52 ppm, with J Pt,H coupling constants ranging from 59.6 to 80.4 Hz), and ( iii ) ( 13 C{ 1 H} NMR) the expected resonances for the C=N (a singlet at δ C = 151.5 ppm) and Me carbons (three singlets at δ C = 6.6, 7.8 and 8.9 ppm, with J Pt,C coupling constants ranging from 535.7 to 643.7 Hz).…”

Heterotridentate Organomonophosphines in Pt(κ3–X1P1X2)(Y) (X1,2 = N1,2 or S1,2), Pt(κ3–P1N1X1)(Y) (X1 = O, C, S or Se) Pt(κ3–P1S1Cl1)(Cl) and Pt(κ3–P1Si1N1)(OL)—Structural Aspects

“…There are two monoclinic complexes [Pt{κ 3 -Ph 2 P 1 (C 7 H 6 N 1 = NCC 1 C 5 H 6 )}(Cl)] (Figure 2) (at 120 K) [20] and [Pt{κ 3 -Ph 2 P 1 (C 7 H 5 N 1 )(C 7 H 8 C 1 )}(py)].BF 4 (at 100 K) [21] (Table 1 (C: Pt(κ 3 -P 1 N 1 C 1 )(Y))). In the former complex, the κ 3 -P 1 N 1 C 1 ligand forms two fivemembered metallocyclic rings of the P 1 C 2 N 1 NCC 1 type, with the values of the chelate rings of 85.2 • (P 1 -Pt-N 1 ) and 78.7 • (N 1 -Pt-C 1 ), respectively.…”
