Abstract

Diethyl 5‐isopropenyl‐4,5‐dihydrofuran‐2,3‐dicarboxylate 1a and methyl 5‐isopropenyl‐3‐methoxy‐carbonyl‐4,5‐dihydrofuran‐2‐acetate 2a were prepared by cylization of diethyl 2‐oxosuccinate or dimethyl 3‐oxoglutarate with (E)‐1,4‐dibromo‐2‐methyl‐2‐butene. Their chemical properties were studied.

## Abstract The carboxamides RCONH~2~ [RPh (1), __t__Bu (2)] react with BEt~3~ and with (9H‐9‐BBN)~2~ to give the (acylamino)diethylboranes 3, 4 and the 9‐acylamino‐9‐BBN 5, 6, respectively. Compounds 3 and 4 are largely monomeric (NMR) in solution and dimeric as crystalline solids [X‐ray structur

Perhaps this type of mechanism may be extended to explain the phenomenon of postpolymerization. It has been noted that the applicat

## Abstract Reaction of dithioic acids with dicyclohexylcarbodiimide has been found to give the corresponding bis(thioacyl) sulfides **1** in good yield, which are very useful thioacylating reagents under mild reaction conditions. Most of the aromatic thioanhydrides (**1**, R = aromatic) are fairly
