“…The first suggestion of a C-Hmetal interaction came from the crystal structure of [RuCl,(PPh,),] l 2 as determined by LaPlaca and Ibers13 and shown diagrammatically in 2; the agostic interaction is represented by a single headed arrow.14 Since then many other examples of agostic interaction have been reported and the area has been reviewed. [14][15][16][17][18] We anticipated that an azine phosphine of type 2,E-PPh,CH,C(Bu')=N-N=C(Q)R would displace two PPh, ligands from the labile ruthenium(i1) complex [RuCl,(PPh,),] 2 to give a sixmembered (P-N) chelate, through P and N=C(Q)R nitrogen. This would force the R group to be in close proximity to the metal and induce interaction, i. e. agostic interaction, between a C-H bond in the R group and the ruthenium.…”

Treatment of [RuCI,( PPh,),] 2 with the azine phosphine Z,E-PPh,CH,C( But)=N-N=C( Me) But 3a. derived from MeC(=O) But, gave the 6-agostic tert-butyl complex mer,trans-[RuCI,( PPh,){PPh,CH,-C(Bu')=N-N=C(Me)Bu'}] 4a, in which all nine hydrogens of the tert-butyl group are agostically interacting with ruthenium on the N M R time-scale at 20 "C. The analogous 6-agostic fert-butyl complex mer,trans-[ RuCI,( PPh,){PPh,CH,C( Bu')=N-N=C( H ) But}] 4b was also prepared. Treatment of 2 with the symmetrical azine diphosphine Z,Z-PPh,CH,C( Bu')=N-N=C(Bu')CH,PPh, 5 gave the 6agostic tert-butyl complex mer,trans-[ RuCI,( PPh,){PPh,CH,C( Bu')=N-N=C( Bu')CH,PPh,}] 6, in which one of the PPh, groups is unco-ordinated. Treatment of 2 with the azine phosphine Z,E-PPh,CH,C( Bu')=N-N=C,,H,, 7 , derived from pinacolone-fenchone mixed azine, gave the 6-agostic methyl complex mer,trans-[RuCI,( PPh,){PPh,CH,C( Bu')=N-N=C,,H,,}] 8, in which the methyl group (C'OH,) in the 1 -position of the fenchone residue interacts with ruthenium (fenchone = 1,3,3trimethylbicyclo[2.2.1] heptan-2-one).

Eating and Drinking in Roman Britain

What were the eating and drinking habits of the inhabitants of Britain during the Roman period? Drawing on evidence from a large number of archaeological excavations, this fascinating study shows how varied these habits were in different regions and amongst different communities and challenges the idea that there was any one single way of being Roman or native. Integrating a range of archaeological sources, including pottery, metalwork and environmental evidence such as animal bone and seeds, this book illuminates eating and drinking choices, providing invaluable insights into how those communities regarded their world. The book contains sections on the nature of the different types of evidence used and how this can be analysed. It will be a useful guide to all archaeologists and those who wish to learn about the strength and weaknesses of this material and how best to use it.
