Abstract

A propargylic ester containing a propargylic alkoxy group has been observed to preferentially undergo [1,2]‐acyl shift over [1,3]‐shift. 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]‐H shift over addition to π‐bonds whereas alkynyl platinum carbenoids preferentially add to π‐bonds.

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 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.

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
