Abstract

Reaction of lithiated 1‐(1‐ethoxy‐3‐phenyl‐prop‐2‐ynyl)‐1__H__‐benzotriazole (3) with various acetylenic aldehydes followed by periodinane oxidation and hydrolysis yields terminally protected 1‐phenyl‐1,5‐hexadiyne‐3,4‐diones 7a–d as the first examples of dialkynyl‐1,2‐diones.

## Abstract The dilute solution properties of 4‐phenyl‐1,2,4‐triazoline‐3,5‐dione‐modified polybutadienes were studied in tetrahydrofuran by static and dynamic light scattering and compared with those from unmodified polybutadiene chains. For the unmodified polymer, the scaling laws were establishe
