Abstract
A propargylic ester containing a propargylic alkoxy group has been observed to preferentially undergo [1,2]βacyl shift over [1,3]βshift. In addition, the complementary and contrasting reactivity of vinyl vs. alkynyl platinum carbenoids has been discovered. Vinyl platinum carbenoids are more prone to undergo [1,2]βH shift over addition to Οβbonds whereas alkynyl platinum carbenoids preferentially add to Οβbonds.

Second-order rate constants for substituted benzaldehyde oxime formation increase linearly with the activity of hydrated protons over the pH range ca 2-7. Under these conditions, first-order rate constants show saturation behavior with increasing hydroxylamine concentration, establishing carbinolami
Five aryl-substituted phenacetyl radicals (X = p-MeO, p-Me, H, p-Cl, p-CF 3 ) were generated by laser photolysis of the corresponding dibenzyl ketones in n-hexane and acetonitrile. The decarbonylation reaction was monitored through the rise in time-resolved absorption of the benzyl radical chromopho
The aniline molecule is nonplanar, with its NH 2 group lying at an angle ΞΈ of approximately 42 β’ to the plane of the benzene ring. Substituents on the phenyl ring alter this out-of-plane angle as well as other molecular properties such as the ring bond lengths and angles, the barrier to inversion E
Oligomeric polysiloxanes having the spirobenzopyran moiety and various substituents were prepared. The polymers were photochromic; the color changed from colorless to red on U V irradiation and the color faded on visible irradiation or on standing in the dark. The thermal decoloration was depressed
