The conversion of chemical energy to drive directional motion at the molecular level allows biological systems, ranging from subcellular components to whole organisms, to perform a myriad of dynamic functions and respond to changes in the environment. Directional movement has been demonstrated in artificial molecular systems, but the fundamental motif of unidirectional rotary motion along a single-bond rotary axle induced by metal-catalysed transformation of chemical fuels has not been realized, and the challenge is to couple the metal-centred redox processes to stepwise changes in conformation to arrive at a full unidirectional rotary cycle. Here, we present the design of an organopalladium-based motor and the experimental demonstration of a 360 unidirectional rotary cycle using simple chemical fuels. Exploiting fundamental reactivity principles in organometallic chemistry enables control of directional rotation and offers the potential of harnessing the wealth of opportunities offered by transition-metal-based catalytic conversions to drive motion and dynamic functions.

The diiridium tris(hydrosulfido) complex [Cp*Ir(mu2-SH)3IrCp*]Cl (2; Cp* = eta5-C5Me5) reacted with [NEt4 [SH] at room temperature for 3 h to afford the tetrakis(hydrosulfido) complex [Cp*Ir(SH)(mu2-SH)2IrCp*(SH)] (3). Complex 3 dissolved in benzene is thermally unstable and was converted into the triiridium sulfido-hydrosulfido cluster [(Cp*Ir)3(mu3-S)(mu2-S)(mu2 -SH)2] (4) at 50 C. The related triiridium cluster [(Cp*Ir)3(mu3-S)(mu2-SH)3] Cl (6) was obtained from either the reaction of 3 with 0.5 equiv of [(Cp*IrCl)2(mu2-H)2] or treatment of 2 with an equimolar amount of NEt3. Furthermore, reaction of 3 with 2 equiv of [Pd(PPh3)4 or a [Pd(dba)2]-PPha (dba = dibenzalacetone) mixture gave the Ir2Pd2 mixed-metal sulfido-hydrosulfido cluster [(Cp*Ir)2(SH)(mu3-S)2{Pd(PPh3 )}2(mu2-SH)] (8). X-ray analyses were undertaken to determine the detailed structures of 3, 4, 6, and 8.

A novel palladium-catalyzed interannular selective C-H silylation of 1,1?-biaryl-2-acetamides is described. The combination of palladium catalyst with copper oxidant enables meta- or ortho-selective C-H silylation by employing hexamethyldisilane as a trimethylsilyl source, which relies on the control of NBE derivatives as a switch, thus providing straightforward access to divergent silicon-containing 1,1?-biaryl-2-acetamides.

Despite its industrial importance, very limited mechanistic information on the dehydrogenative coupling of dimethyl phthalate has been reported. Herein we report the detailed mechanism for dehydrogenative coupling of dimethyl phthalate catalyzed by [Pd(OAc)2]/[Cu(OAc)2]/1,10-phenanthroline·H2O (phen·H2O). The solution-phase analysis of the catalytic system by XANES shows the active species to be Pd(II), and EXAFS supports the formation of an (acetato)(dimethyl phthalyl)(phen)palladium(II) complex from [Pd(OAc)2]. A formation pathway of tetramethyl 3,3?,4,4?-biphenyltetracarboxylate via disproportionation of independently prepared [Pd(OAc){C6H3(CO2Me)2-3,4}(phen)] is observed with regeneration of [Pd(OAc)2(phen)].

Two novel phosphane ligands 3 and 4 based on the rigid diphenylglycoluril molecule have been synthesized and characterised. Binding studies with 3 and 4, using 1,3-dihydroxybenzene derivatives reveal that ligands 3 and 4 behave similarly to clip molecule 5, which has the same binding site as ligands 3 and 4. The size of the flexible spacers in the ligands has been varied and the effect of this variation on the association constant of resorcinol denvatives has been determined. These cavity-containing ligands are able to coordinate two transition metal centres, leading to bimetallic macrocycles. The metallamacrocycles formed from 4 containing platinum or rhodium bind the guest, olivetol (5-pentylbenzene-1,3-diol), almost four times as strongly as the free tetrapodant 4. Complexes of 4 having palladium centres display similar or reduced binding affinities for resorcinol derivatives, when compared to free 4. Metal complexes of ligand 3 do not form host-guest complexes, probably because of a too small a ring-size of the metallamacrocycle.

Three new triarylphosphines were prepared that have a 2,3,4,5- tetraphenylphenyl (TPPh) moiety on one of the phenyl rings (at the ortho, meta, or para position) of triphenylphosphine. Among them, the ortho derivative is particularly effective to utilize unactivated aryl chlorides in three different palladiumcatalyzed reactions, i.e., Suzuki-Miyaura coupling, Mizoroki-Heck reaction, and silylation with Me3SiSiMe3. On the other hand, the corresponding meta and para derivatives are not effective as ligands at all in these catalytic reactions. X-ray crystal structures of Pd(0) complexes having the effective phosphines (ortho derivatives) as ligands show that eta2-coordination on the TPPh moiety is general and operative to realize a highly active catalyst system.
