Syntheses of 1,5-Bisphenyl-1,5-bis(p-chlorophenyl)- and 1,1,5,5-Tetraphenyl-pentane-3-carboxylic Acids, Esters and Other Derivatives

Convinient syntheses of 1,5-bisphenyl-1,5-bis(p-chlorophenyl)- and 1,1,5,5-tetraphenyl-pentane-3-carboxylic acids, esters, alcohols and the corresponding aldehydes are described.

The Reaction of Olefins with Malonic Acid in the Presence of Manganese(III) Acetate

The reaction of 1,1-diphenylethene with malonic acid in the presence of manganese(III) acetate gave 3,3,8,8-tetraphenyl-2,7-dioxaspirononane-1,6-dione and 4,4-diphenyl-2-(2,2-diphenylethenyl)-4-butanolide.Similar reactions with 1,1-bis(4-methoxyphenyl)ethene, methylenecyclohexane, 2-phenylpropene, 1-octene, and cyclohexene yielded the corresponding 2,7-dioxaspirononane-1,6-diones.
