The Action of Diiodoacetylene on Organic Bases.

Abstract

Bromoaurate, coarse, red-brown prisms melting a t 190'. Calculated for C,HSNH,.HBr.AuBr,: Au, 35.03. The second compound referred to is easily soluble in chloroform: on treating with water, insoluble carbon tetrabromide was formed. From boiling chloroform beautifid prismatic needles melting a t I 50' were obtained. Found: Br, 6 3-3 9 .

High-Pressure Behavior of C2I2 and Polymerization to a Conductive Polymer

“…Crystals of C 2 I 2 were synthesized by a modified method of Dehn, the principle reaction mechanisms being the same, but the scale being reduced. Other methods of synthesis include those of Berend, Biltz and Küppers, Nef, and Vaughn and Nieuwland .…”
