Iridium(I) complexes of phenanthroline-derived benzimidazolylidenes : synthetic, structural and catalytic studies

N-heterocyclic carbenes (NHCs) have undergone rapid development in recent years. Due to their strong a-electron donation and structural variability properties, NHCs are becoming a major class of ligands in organometallic chemistry. Compared with the other two types of NHCs (imidazolylidenes and imidazolinylidenes), benzimidazolylidenes have not been well represented. Limited synthetic approaches may impede the development ofbenzimidazolylidenes. This thesis is focused on the synthesis of phenanthroline-derived benzimidazolylidene ligands and their metal complexes. A series of benzimidazolylidene-iridium complexes were synthesized and characterized spectroscopically and crystallographic ally. All of the new complexes showed varying degrees of catalytic activity and enantioselectivity toward transfer hydrogenation and asymmetric hydrogenation. The best results were achieved in hydrogenation of methyl-2-acetamidoacrylate, which afforded (-)-(R)-methyl-2-acetamidopropanoate in 97% yield and 81 % ee.

Beyond child's play : wealth, status, and the death of children in the MH-LH I periods of the Argolid, Greece

This study explores the mortuary remains of children from the MH-LH I periods of the Argolid, Greece. This examination concentrates on how the child in death acted as a tool for wealth and status display. Here, children are understood to have perpetuated, maintained, and reinforced status distinctions between families in their community. The analysis of one hundred child burials that date to these periods illustrates how the burials of children were important opportunities used by the families of children to display wealth and status. Thus, children can be viewed as important factors in the reorganization of social structure in the transition from the Middle to Late Helladic.

Asymmetric hydrogenation of alkenes with cationic iridium(I) complexes of 2-phosphino-1-aminoferrocene ligands

Iridium complexes with bidentate P,N ligands represent a class of catalysts that significantly expand the application range of asymmetric hydrogenation. New substrate classes, for which there have previously been no suitable catalysts, can now be efficiently hydrogenated in high conversion and enantioselectivity. These substrates are often of synthetic importance, thus iridium catalysis represents a significant advance in the field of asymmetric catalysis. Planar chiral ferrocenyl aminophosphine ligands in which both heteroatoms were directly bound to the cyclopentadienyl ring were prepared by BF3-activated lithiationsubstitution in the presence of a chiral diamine in 49-59% yield and 75-85% enantiomeric excess. Some of these ligands were recrystallized to enantiomeric purity via ammonium fluoroborate salt formation of the phosphine sulfide. A crystal structure of one of these compounds was obtained and features an intramolecular hydrogen bond between the nitrogen, hydrogen, and sulfur atoms. Neutralization, followed by desulfurization, provided the free ligands in enantiomeric purity. Iridium complexes with these ligands were formed via reaction with [Ir(COD)Clh followed by anion exchange with NaBArF. These complexes were successfully applied in homogeneous hydrogenation of several prochiral substrates, providing products in up to 92% enantiomeric excess. Variation of the dimethyl amino group to a pyrrolidine group had a negative effect on the selectivity of hydrogenation. Variation of the substituents on phosphorus to bulkier ortho-tolyl groups had a positive effect, while variation to the more electron rich dicyclohexyl phosphine had a negative effect on selectivity.

Small Cabinet Card of African American Man by John S. Thom, of Lucan, Ontario [n.d.]

A very small cabinet card type photograph of an unidentified man, possibly a relative of the Bell - Sloman family. A handwritten entry on the reverse of the photograph indicates it was taken by John S. Thom, of Lucan. No date is provided, however, John S. Thom is known to have been a photographer in Lucan from 1877-1882. This cabinet card was in the possession of Iris Sloman Bell, of St. Catharines. Relatives of the Sloman - Bell family include former African American slaves who settled in Canada.John S. Thom is listed as a photographer in Lucan, Ontario from 1877-1882. Aside from photography, he also operated a general store and sold notions. It appears he then moved to Sarnia, Ont. and is listed as a photographer there from 1882-1900. He is also recorded as being a Sarnia bicycle dealer. Source: Phillips, Glen C. The Ontario photographers list (1851-1900). Sarnia: Iron Gate Publishing Co., 1990.
