Photolysis of [Re(η 5 -C H 4 R)(CO) 3 ] (R = or Me) in hexafluorobenzene yielded 2 ( η 6 F )] containing the -co-ordinated arene. The complex has been characterised crystallographically. It forms monoclinic crystals space group P2 1 /n with Z 4, a 7.926(2), b 12.179(4), c 13.675(4) Å and β 102.91(2)°. structure reveals expected features distortion C unit from planarity at co-ordinated C–C bond. rhenium lies 2.059(7) mid-point bond .

UV irradiation of [(η5-C5Me5)Re(CO)2N2] in neat 1,4-C6H4F2 generates a mixture the C–H activation product trans-[(η5-C5Me5)Re(CO)2(2,5-C6H3F2)H] 1a and η2-arene complex [(η5-C5Me5)Re(CO)2(2,3-η2-1,4-C6H4F2)] 2a, identified on basis their IR NMR spectra. Reaction with CHBr3 allowed isolation trans-[(η5-C5Me5)Re(CO)2(2,5-C6H3F2)Br] 1a–Br; subsequent reaction LiBEt3H followed by HCl at low temperature provided an independent route to free 2a. Nevertheless, converts 2a above 213 K. NOESY/EXSY...
The UV irradiation of [Re(η5-C5Me5)(CO)3] in the presence C6F6 effected intermolecular C–F and intramolecular C–H activation generating [Re(η6-C5Me4CH2)(CO)2(C6F5)] 1a two isomeric forms. In major isomer CH2 group lies trans to C6F5 both solution crystal. minor cis group. A similar reaction with C6F5CF3 generates [Re(η6-C5Me4CH2)(CO)2(C6F4CF3)] 1b four form CF3 is 4 position C6F4CF3 other three isomers are formed by rotation η6-C5Me4CH2 ligand as above, placing at 3 position, a combination...
Photochemical reaction of [Re(η5-C5Me5)(CO)3] with hexafluorobenzene yields [Re(η6-C5Me4CH2)(CO)2(C6F5)] formed by insertion into a C–F bond C6F6 and concomitant methyl C–H bond; the reactions PMe3 HCl show that (η6-C5Me4CH2) ligand is subject to both nucleophilic electrophilic attack.
The synthesis and characterization of two novel isomeric hybrid ferrocenyl/cyrhetrenyl aldimines [(η5-C5H5)Fe{(η5-C5H4)-CH[double bond, length as m-dash]N-(η5-C5H4)}Re(CO)3] (1) [(η5-C5H5)Fe{(η5-C5H4)-N[double m-dash]CH-(η5-C5H4)}Re(CO)3] (2) are reported. Their X-ray crystal structures reveal that both adopt the E form. However, molecules 1 2 differ in relative arrangement "Fe(η5-C5H5)" "Re(CO)3" units (anti syn 2). This affects type intermolecular interactions, assembly therefore their...
UV Irradiation of [Re(η5-C5R5)(CO)3] (R = Me or H) in the presence C6F5H 1,2,4,5-C6F4H2 effected intramolecular C–H activation, generating hydrido complexes trans-[Re(η5-C5R5)(CO)2(Ar)FH] [(Ar)F C6F5 2,3,5,6-C6F4H] as principal photochemical products. The identities were confirmed by independent thermal syntheses. photoreaction [Re(η5-C5Me5)(CO)3] with also generated fulvene complex [Re(η6-C5Me4CH2)(CO)2(C6F5)] 2a and two bis(aryl) derivatives: cis-[Re(η5-C5Me5)(CO)2(C6F5)2] 3a...
