The preparation and reactions of some 1, 2-dipolar species /|nI. D. Brindle. -- 260 St. Catharines, Ont. : [s. n.],

This research was directed mainly towards the investigation of the reactions of allylic amineimides. The work can be divided into two main sections. Section 1 of the thesis deals mainly with thermolysis studies of amineimides. Sections 1a and 1b represent a comprehensive survey of amineimide literature up to 1971. N-A1ly1-N,N-dirnethylarnine-benzirnide was prepared and rearranged at 1400 to l-allyl-1-benzoyl-2,2-dimethylhydrazine. A tentative mechanism involving an initial migration to the carbonyl oxygen was disproved by incorporating the amineimide system into a five-membered ring. N,N~Dimethyl-N-propargylamine-benzimidedid not rearrange on heating; but the hydrobromide, on heating, disproportionated to give 1-benzoyl~2,2,2-trimethylhydraziniumbromide and I-benzoyl-2,2~ dimethylhydrazine. l-Ally'l--l, I-dimethyl-2-benzoy-lhydrazinium bromide and 1~benzoy-1-2,2, 2-trimethy-lhydrazinium iodide both disproportionated to give l~benzoyl-2,2-dimethylhydrazine. Section 1 concludes with a discussion of the mechanisms of ally'lic migrations in amineimides proposed by J. E. Baldwin. Section 2 deals with the formation of five-membered heterocyclic compounds from amineimides by bromination. 1,1-Dimethyl-2benzoyl- 4-bromopyrazolidinium bromide was formed from N-allyl-N,Ndime thy-lamtne-benzimide , 1,1-dimethyl-2-benzoyl-4-bromopyrazol-3enium bromide from N,N~dimethyl-N-propargylamine~benzimidevia the unusual acetylenic "bromonium" ion. Hydrogenolysis of both heterocyclic compounds gave the same product. The preparation was extended by forming 2,2-dimethyl-4-bromoisoxazolinium bromide from N-allylN, N-dimethylamine-N-oxide. Sections 3 and 4 cover a number of unsuccessful attempts to synthesise other amineimides and l,2-dipolar species.

The Military Monitor and American Register- 1 February 1813

The Military Monitor was a weekly periodical that was published every Monday. The first issue was printed for August 17, 1812 and is believed to have ceased in 1814, as the last issue located was April 2, 1814. The periodical was suspended with the November 23, 1812 issue and resumed with the December 14, 1812 issue. The quote at the top of the first page is "The public good our end". The periodical's various authors included: Desnoues, Joseph, 1794?-1837. O'Connor, Thomas, 1770-1855. Hardcastle, John, 1778?-1835. Van Pelt, Peter, 1779?-1843. Wall, Stephen. Van Riper, Nicholas. Other authors are believed to be the American Antiquarian Society. Proprietors: T. O'Connor and S. Wall, 1812; T. O'Connor, 1812- . Printers: Hardcastle and Van Pelt, for T. O'Connor and S. Wall, Sept. 14-Oct. 5, 1812; J. Desnoues, Oct. 12, 1812- ; N. Van Riper, Nov. 6, 1813- . This issue was included in a bound volume of the Military Monitor and American Register.

Palynology and foraminiferal geochemistry of the Lower Pleistocene Olduvai Subchron (ca. 1.8 Ma) in DSDP Hole 603C, western North Atlantic

Marine palynology and benthic and planktonic foraminiferal geochemistry are combined to reveal long- and short-term (Milankovitch-scale) paleoceanographic changes across the upper half of the Olduvai Subchron (ca. 1.86--1.77 Ma, lower Pleistocene) in DSDP Hole 603C from the lower New Jersey continental rise. Planktonic foraminiferal Mg/Ca ratios reveal annual sea-surface temperatures between 14.5° and 25°C, whereas modern values vary between 16° and 20°e. Despite evidence of downslope transport in much of the studied interval, dinoflagellate cyst and acritarch assemblages appear to reflect fluctuating temperate to subtropical water masses. These assemblages comprise both neritic and oceanic species, and are marked by a transition upsection from warm conditions, dominated by Lingulodinium machaerophorum, Polysphaeridium zoharyi and Cymatiosphaera? invaginata, to cooler conditions dominated by Filisphaera filifera. Combining dinoflagellate cyst proxies with planktonic foraminiferal geochemistry allows downslope transport events to be recognized during glacial episodes, and events dominated by intensified bottom-water circulation during interglacial episodes. Sixtytwo in-situ dinoflagellate cyst and acritarch taxa were recorded including several not previously described.
