“…Use of SbPhCl2 resulted in clusters containing µ 3 -SbPh groups. Attempts to isolate a complex of SbPh2Cl with Ru3(CO)12 failed, but reduction of Ru3(CO)12 with the benzophenone ketyl radical, followed by addition of SbPh2Cl, gave [Ru6(CO)20(µ 2 -SbPh2)2], which has a raft structure [32].…”

“…Other compounds are reported within the Os–Sb and Ru–Sb systems, but with lower nuclearity. In the neutral Os 3 (SbPh 2 ) 2 (CO) 10 and Ru 6 (SbPh 2 ) 2 (CO) 20 , the SbPh 2 groups act as bridging ligands on the metal surface, while in both Os 6 (μ 5 -Sb)(μ-H) 2 (μ-SbPh 2 )(μ 3 ,η 2 -C 6 H 4 )(CO) 17 and Ru 6 (μ 5 -Sb)(μ-H) 3 (SbPh 3 )(CO) 18 , the naked Sb atom connects two cluster fragments.…”

The reactivity of [Rh 7 (CO) 16 ] 3– with SbCl 3 has been deeply investigated with the aim of finding a new approach to prepare atomically precise metalloid clusters. In particular, by varying the stoichiometric ratios, the reaction atmosphere (carbon monoxide or nitrogen), the solvent, and by working at room temperature and low pressure, we were able to prepare two large carbonyl clusters of nanometer size, namely, [Rh 20 Sb 3 (CO) 36 ] 3– and [Rh 21 Sb 2 (CO) 38 ] 5– . A third large species composed of 28 metal atoms was isolated, but its exact formulation in terms of metal stoichiometry could not be incontrovertibly confirmed. We also adopted an alternative approach to synthesize nanoclusters, by decomposing the already known [Rh 12 Sb(CO) 27 ] 3– species with PPh 3 , willing to generate unsaturated fragments that could condense to larger species. This strategy resulted in the formation of the lower-nuclearity [Rh 10 Sb(CO) 21 PPh 3 ] 3– heteroleptic cluster instead. All three new compounds were characterized by IR spectroscopy, and their molecular structures were fully established by single-crystal X-ray diffraction studies. These showed a distinct propensity for such clusters to adopt an icosahedral-based geometry. Their characterization was completed by ESI-MS and NMR studies. The electronic properties of the high-yield [Rh 21 Sb 2 (CO) 38 ] 5– cluster were studied through cyclic voltammetry and in situ infrared spectroelectrochemistry, and the obtained results indicate a multivalent nature.

“…The main challenge in functionalization of C-H bonds is controlling which C-H bond would undergo activation or cleavage or site-selectivity [3,4]. One approach to help provide regiocontrol is the use of groups that can direct the reaction to occur at a specific C-H bond.…”

In the present Short Note, we report a synthesis for the title compound, N-(9,10-dioxo-9,10-dihydroanthracen-1-yl)-2-methylbenzamide by reacting 2-methylbenzoyl chloride (or 2-methylbenzoic acid) with 1-aminoanthraquinone. The synthesized target compound was fully characterized by various spectroscopic methods (1H-NMR, 13C-NMR, IR, GC-MS). The importance of this compound lies its possession of an N,O-bidentate directing group, potentially suitable for metal-catalyzed C-H bond functionalization reactions.
