Ring-Methyl Activation in Pentamethylcyclopentadienyl Complexes. 8.¹ Introduction of Organic Functionalities at Substituted Tetramethylcyclopentadienyl Complexes of Ruthenium(II)

Organometallics (1998)

D. R. KNOWLES Harry Adams Peter M. Maitlis

A series of complexes derived from nucleophilic attack at the CH2Cl of [(η5-C5Me4CH2Cl)Ru(CO)2Cl], 1, by a wide variety of organic reagents are described. Most reactions proceed in good yield and do not appear to affect the Ru(CO)2Cl group, even though they are performed under quite stringent (oxidizing, acidic, or hydrolytic) conditions. Hydrolysis of 1 in the presence of collidine gives the alcohol complex, [(C5Me4CH2OH)Ru(CO)2Cl], 2, which is oxidized (Me2SO, oxalyl chloride) to [(C5Me4CHO)Ru(CO)2Cl], 4a, and which can be further oxidized (KMnO4) to [(C5Me4CO2H)Ru(CO)2Cl], 10. The alcohol complex 2 forms esters [(C5Me4CH2O2CR)Ru(CO)2Cl], 3 (R = Me, CH2CH, 2-furyl, and 2-thienyl), on reaction with RCOCl/Et3N. The aldehyde 4a is a very versatile starting material: It forms acetals such as [(C5Me4CH(OCH2)2)Ru(CO)2Cl], 5a, with ethylene glycol. It reacts with phenylhydrazine and p-toluidine in the presence of acid to give [(C5Me4CHNNHPh)Ru(CO)2Cl], 6, and [(C5Me4CHN-p-To)Ru(CO)2Cl], 7. It also reacts with carbon nucleophiles such as PhMgBr to give [(C5Me4CH(OH)Ph)Ru(CO)2Cl], 8a, with lithium enolates to give [(C5Me4CH(OH)R)Ru(CO)2Cl], 8b−d (R = 2-oxocyclohexyl, MeCOCH2, and PhCOCH2), and with Wittig reagents to give [(C5Me4CHCHR)Ru(CO)2Cl], 9 (R = EtCO2, Ph, MeCO, and PhCO). The carboxylic acid 10 forms the acid chloride [(C5Me4COCl)Ru(CO)2Cl], which reacts with diisopropylamine to give the amide [(C5Me4CON(i-Pr)2)Ru(CO)2Cl], 12. The structures of complexes [(C5Me4CH(OH)Ph)Ru(CO)2Cl], 8a, [(C5Me4CH(OH)CH2COPh)Ru(CO)2Cl], 8d, and [(E-C5Me4CHCHPh)Ru(CO)2Cl], 9b, have been confirmed by X-ray determinations.

Pentamethylcyclopentadienyl-rhodium and -iridium complexes. Part X. The kinetics of the reactions of some cyclic and acyclic dienes with µ-hydrido-compounds

Journal of the Chemical Society. Dalton transactions (1975)

Hing‐Biu Lee K. Moseley Colin White Peter M. Maitlis

The µ-hydrido-complexes [{M(C5Me5)}2HCl3](2a; M = Rh) and (2b; M = Ir) react readily with cyclo-octa-1,3- and -1,5-diene, cyclohexa-1,3- and -1,4-diene, to give the cyclic η-allylic complexes which reductively decompose to give [MI(C5Me5)diene]. The rate of the reaction of the hydride with a variety of cyclic and acylic dienes was shown to be first order in hydride and zero order in diene and to be independent of the nature of the diene. The rate-determining step is proposed to be opening of the metal-halide and not the metal-hydride bridge of (2). Cyclopentadiene gives a cyclopentenyl complex with (2), but this loses 2 H to give [MIII(C5Me5)(C5H5)]+; norbornadiene gives a σ,η-norbornenyl complex that reductively eliminates to [MI(C5Me5)(norbornadiene)]. The reactions of the hydrido-complexes (2) with dienes are compared with those of [(MC5Me5Cl2)2] in alcohol–base.

The parallel between phenyl-initiated C–C coupling reactions in dirhodium complexes and those catalysed by rhodium particles

Journal of the Chemical Society Chemical Communications (1995)

Zhi-Qiang Wang Helen C. Long Michael L. Turner Peter M. Maitlis

Decomposition of [{(C5Me5)Rh(µ-CH2)}2(Ph)(CO)]+(homogeneously, under CO) in solution gives PhCHCH2, PhMe and C6H6, while phenyl (from Phi) reacts with surface methylene (from CO + H2) heterogeneously over rhodium metal to give PhEt, PhMe and C6H6; it is proposed that the two reactions are also related mechanistically.

Journal of the Chemical Society Chemical Communications (1974)

Pamela M. Bailey B. E. MANN A. Segnitz Klaus L. Kaiser Peter M. Maitlis

The structure of the t-butylacetylene trimer complex [Pd{Cl(Me3CC2H)3}Cl]2(I) has been elucidated from its 1H and 13C n.m.r. spectra as well as by an X-ray structure determination of its triphenylphosphine adduct, [Pd{Cl(Me3CC2H)3}Cl(PPh3)]; complex (I) exists in two η3-allylic forms, an exocyclic and an endocyclic one, which interconvert.
