(Massachusetts Institute of Technology, 2011)
I. N-Isopropylidene-N'-2-Nitrobenzenesulfonyl Hydrazine. A Reagent for Reduction of Alcohols via the Corresponding Monoalkyl Diazenes The development of a new reagent N-isopropylidene-N'-2-nitrobenzenesulfonyl hydrazine ...
Molecular design of conjugated polymers for the control of conformation, electronics and self-assembly
(Massachusetts Institute of Technology, 2008)
The design, synthesis and characterization of organic electronic materials, in particular luminescent conjugated polymers, with structural motifs that allow for the controlled modulation of their photophysical properties ...
Cyclopropene polymerization and enyne metathesis catalyzed by high oxidation state molybdenum alkylidenes
(Massachusetts Institute of Technology, 2008)
Chapter 1. An olefin metathesis reaction between Mo(NAr)(CHCMe2Ph)(OCMe(CF3)2)2 (Ar = 2,6diisopropylphenyl) and trans-i 1,4-divinylbenzene or trans, trans- 1,4-di-buta- 1,3-dienylbenzene (5) results in the formation of ...
An experimental study of OH uptake by surfaces of tropospheric importance under dry and wet conditions
(Massachusetts Institute of Technology, 2008)
The effect of relative humidity (RH) on OH uptake by surfaces of tropospheric importance was investigated. Due to diffusion limitation conditions, experiments were performed with parallel reactors packed with beads and ...
Syntheses and studies of group 6 terminal pnictides, early-metal trimetaphosphate complexes, and a new bis-enamide ligand
(Massachusetts Institute of Technology, 2011)
Investigated herein is the reactivity of the terminal-nitrido, trisanilide tungsten complex, NW(N[i- Pr]Ar)3 (Ar = 3,5-Me 2C6H3, 1). Nitride 1 has been shown to undergo an "N for (O)C1 metathesis with a variety of acid ...
Colloidal CdSe/CdS nanostructures : synthesis, optical characterization and applications
(Massachusetts Institute of Technology, 2016)
The focus of this thesis is the study of CdSe/CdS nanostructures, from their fundamental properties to their integration in practical devices. This material system has proven to be remarkably robust both as a platform for ...
Synthesis, characterization and reactivity of organometallic Zr(IV) carboxylate and titanium aminotroponiminate complexes
(Massachusetts Institute of Technology, 1999)
The synthesis and structure of several Zr(IV) carboxylate complexes are described in which the bridging carboxylate is the dianion of 111-xylylenediamine bis(Kemp's triacid imide) (H2XDK) or the more soluble propyl derivative ...
Spectroscopic investigations of the X and A state dynamics of ¹³C₂H₂
(Massachusetts Institute of Technology, 2002)
The objective of the experiments described in this thesis is to perform a detailed spectroscopic study of the dynamics on the A and X state surfaces of 13C2H2 in order to further understand the acetylene - vinylidene ...
Complexation, coupling, and cleavage of organonitriles, alkynes, dinitrogen, hydrostannanes or phosphines by three-coordinate molybdenum(III) complexes
(Massachusetts Institute of Technology, 2002)
The biosynthetic Claisen condensation : mechanistic enzymology of biosynthetic thiolase from Zoogloea ramigera
(Massachusetts Institute of Technology, 1987)
