Storage & Sensitivity
Moisture Sensitive. Air Sensitive. Ambient temperatures.
Soluble in acetone and acetonitrile. Insoluble in water


Copper(I) phenylacetylide participates in efficient coupling with a range of aryl iodides and bromides to give substituted tolanes which, if possessing an ortho amino or hydroxy group, can be thermolyzed to yield 2-phenylbenzofurans, -indoles, and -furo[3,2-b]pyridines.


Store in a cool dry place in tightly closed containers. Incompatible with oxidizing agents.

GHS Hazard and Precautionary Statements

Hazard Statements: H250-H260-H314-H335-X

Catches fire spontaneously if exposed to air. In contact with water releases flammable gases which may ignite spontaneously. Causes severe skin burns and eye damage. May cause respiratory irritation.

Precautionary Statements: P210-P222-P223-P231+P232-P235+P410-P260-P264b-P271-P280-P301+P330+P331-P303+P361+P353-P304+P340-P305+P351+P338-P310-P335+P334-P363-P370+P378q-P501c

Keep away from heat/sparks/open flames/hot surfaces. - No smoking. Do not allow contact with air. Keep away from any possible contact with water, because of violent reaction and possible flash fire. Handle under inert gas. Protect from moisture. Keep cool. Protect from sunlight. Do not breathe dust/fume/gas/mist/vapours/spray. Wash face, hands and any exposed skin thoroughly after handling Use only outdoors or in a well-ventilated area. Wear protective gloves/protective clothing/eye protection/face protection.
