A dramatic isotope effect in the reaction of ClSiH with trimethylsilane-1-d: experimental evidence for intermediate complexes in silylene Si-H(D) insertion reactions

A kinetic isotope effect (kD/kH) of 7.4 has been found for the reaction of chlorosilylene with trimethysilane (Me3SiD vs Me3SiH). Such a value can be accounted for by theoretical modelling, but only if an internal rearrangement of the initially form complex is included in the mechanism. This provides the first concrete evidence for such complexes.

Arthur Miller: Spirituality Explored

Following the overview of his life, I will discuss in depth various theme that Miller presents in his writing by closely analyzing four of Miller's plays. I will give you a brief setting into which Miller wrote the various plots.

Politian: a critical analysis

Why even look at Politian, an unfinished failure? While it is true that Politian was a failure for its time and surely one of Poe's least successful attempts, it may improve on a stage with a more modern perspective. If not solely for examination of Poe's artistic effort, Politian also warrants a closer read due to its historical relevance by way of Beauchamp and Sharp. Poe, a most fastidious editor of his work, was ultimately required because of financial constraints to lay aside Politian in its unfinished state. As a result, the unedited Politian may provide insight into the writing process of Poe that other polished pieces cannot, and that, if nothing else, warrants a more precise study of his play.
