The "Columbian" was established by Mr. Holt in 1808 as an "organ of the Clintonians" (Journalism in the United States, from 1690-1872 By Frederic Hudson) and a replacement to the "Citizen". It was a passionate Democratic paper that supported both Jefferson and Madison. Holt later sold the "Columbian" to Alden Spooner, who published the Long Island "Star". The Columbian ceased in 1821. This issue includes the following War of 1812 topics: Page 2: copies of letters from U.S. Gen. H. Dearborn describing the U.S. attack on Ft. George 27 May 1813; letter from Gen. H. Dearborn describing U.S. pursuit of British troops at Beaver Dams and the U.S. capture of Fort Erie; list of U.S. killed and wounded in Commodore Isaac Chauncey's squadron in attack on York 27 April, 1813; list of killed and wounded in Commodore Isaac Chauncey's squadron in attack on Ft. George 27 May 1813; abstract of the cartel for the exchange of prisoners of war between Great Britain and the United States; mention of troop movements through New York on their way to the battle front; list of persons killed or lost on the privateer Saratoga; Page 3: account of the loss of the U.S. war ships the Growler and Eagle to the British; news from Quebec and Kingston of troop movements; U.S. ship Syren unsuccessfully pursues British ship Herald; account of a U.S. cargo ship being captured by a British military ship; account of U.S. ship Siro capturing British ship Loyal Sam; report from Halifax of recent British troop and ship movements; list of recent troop enrollments in various states; report of British troop build up in Kingston;

This thesis describes the synthesis, structural studies, stoichiometric and catalytic reactivity of novel Mo(IV) imido hydride complexes (Cp)(ArN)Mo(H)(PMe3) (1) and (Tp )(ArN)Mo(H)(PMe3) (2). Both 1 and 2 catalyze hydrosilylation of a variety of carbonyls. Detailed kinetic and DFT studies found that 1 reacts by an unexpected associative mechanism, which does not involve Si-H addition either to the imido group or the metal. Despite 1 being a d2 complex, its reaction with PhSiH3 proceeds via a a-bond metathesis mechanism giving the silyl derivative (Cp )(ArN)Mo(SiH2Ph)(PMe3). In the presence of BPh3 reaction of 1 with PhSiH3 results in formation of (Cp)(ArN)Mo(SiH2Ph)(H)2 and (Cp)(ArN)Mo(SiH2Ph)2(H), the first examples ofMo(VI) silyl hydrides. AI: 1 : 1 reaction between 2, PhSiD3 and carbonyl substrate established that hydrosilylation is not accompanied by deuterium incorporation into the hydride position of the catalyst, thus ruling out the conventional mechanism based on carbonyl insertion carbonyl. As 2 is nomeactive to both the silane and ketone, the only mechanistic alternative we are left with is that the metal center activates the carbonyl as a Lewis acid. The analogous nonhydride mechanism was observed for the catalysis by (ArN)Mo(H)(CI)(PMe3), (Ph3P)2(I)(O)Re(H)(OSiMe2Ph) and (PPh3CuH)6. Complex 2 also catalyzes hydroboration of carbonyls and nitriles. We report the first case of metal-catalyzed hydroboration of nitriles as well as hydroboration of carbonyls at very mild conditions. Conversion of carbonyl functions can be performed with high selectivities in the presence of nitrile groups. This thesis also reports the first case of the HlH exchange between H2 and Si-H of silanes mediated by Lewis acids such as Mo(IV) , Re(V) , Cu(I) , Zn(II) complexes, B(C6Fs)3 and BPh3.
