Chapter III describes a series of 1,3-, 2,5-, and 2,4-dimethylene five-member heterocycles as new ferromagnetic coupling units. Full geometry optimization of structures with heteroatoms ranging from Be to O and from Mg to ...

The first synthesis of the 1,3-diazabiphenylene ring system by cobalt-catalyzed cooligomerization of a novel diethynylpyrimidine and bis(trimethylsilyl)acetylene is described. This diazabiphenylene is found to undergo an ...

The compound 1-(1H-pyrrol-2-yl)-1,2-propanedione was recently found to be an important pheromone component of several Asian species of longhorned beetles in the subfamily Cerambycinae. Here, we report the first confirmed ...

The {3,3}sigmatropic rearrangement of N-alkyl-N-aryl-O-acetoacetylhydroxylamines gives N-alkyl indoles in moderate yields under mild conditions. The substituted hydroxylamines were prepared by the condensation of aldehydes ...

We determine the existence of 1-factorizations of certain tensor products of graphs. The properties of these 1-factorizations are of interest; to study them, we develop results about the automorphism group of tensor products ...

A 1-GS/s, 14-bit track-and-hold amplifier (THA) has been studied as the second half of this dissertation research. The THA is a key subcircuit in a data acquisition and conversion system. The input buffer of the THA employs ...

Format and number of attempts were varied in online pre-lecture quizzes administered to a first semester non-majors organic chemistry lecture course. Student quiz performance and post-quiz assessment shows significant ...
