VB can be produced by the catalytic addition of hydrogen
bromide to acetylene in the presence of mercury and
copper halide catalysts or by partial dehydrobromination
of ethylene dibromide with alcoholic potassium
hydroxide.
General Description
Boiling point 60°F. Liquid at low ambient temperatures. Specific gravity 1.51. A suspected carcinogen. Under exposure to fire or heat containers may rupture violently and rocket.
Air & Water Reactions
Highly flammable, with air forms peroxides
Reactivity Profile
VINYL BROMIDE is a light sensitive, peroxidizable monomer may initiate exothermic polymerization of the bulk material [Handling Chemicals Safely 1980.. p. 958]. Vinyl bromide will react violently with oxidants.
Health Hazard
Different sources of media describe the Health Hazard of 593-60-2 differently. You can refer to the following data:
1. Vapors may cause dizziness or asphyxiation without warning. Some may be toxic if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases.
2. Inhalation of this gas at high concentrationscan produce anesthesia and kidney damage.Exposure to 2.5% concentration in air pro duced anesthetic effects in rats. A 15-minuteexposure to 10% concentration was fatal torats (ACGIH 1986). Kidney injury occurredat a 5% exposure level. Human toxicity datafor this compound are not available. The liq uid is mild to moderately irritating to theeyes.Vinyl bromide manifested carcinogenicproperties in laboratory animals. It producedliver and blood tumors in rats and mice.Its cancer-causing effects in humans arenot known. However, on the basis of itssimilarity to vinyl chloride, it is suspectedto be a human carcinogen.
Fire Hazard
EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Silane will ignite spontaneously in air. May polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.
Safety Profile
Confirmed carcinogen
with experimental carcinogenic,
neoplastigenic, and tumorigenic data.
Moderately toxic by ingestion. Mutation data
reported. A very dangerous fire hazard when
exposed to heat or flame. Can react violently
with oxidzing materials. May polymerize in
sunlight. To fight fire, use CO2, dry
chemical, or water spray. When heated to
decomposition it emits toxic fumes of Br-.

CHLORIDE.
Potential Exposure
Vinyl bromide is used as an intermediate
in organic synthesis and for the preparation of plastics
by polymerization and copolymerization; as a comonomer
with acrylonitrile and other vinyl monomers in modacrylic
fibers; in the production of flame-retardant synthetic fibers.
Carcinogenicity
Vinyl bromide is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.
Shipping
UN1085 Vinyl bromide, stabilized, Hazard
Class: 2.1; Labels: 2.1-Flammable gas. Cylinders must be
transported in a secure upright position, in a well-ventilated
truck. Protect cylinder and labels from physical damage.
The owner of the compressed gas cylinder is the only entity
allowed by federal law (49CFR) to transport and refill
them. It is a violation of transportation regulations to refill
compressed gas cylinders without the express written permission
of the owner.
Incompatibilities
Vinyl bromide is a dangerous chemically
unstable compound that may polymerize spontaneously in
heat, sunlight and possibly exposure to UV. Dangerously
reactive with oxidizers (chlorates, nitrates, peroxides, permanganates,
perchlorates, chlorine, bromine, fluorine, etc.);
contact may cause fires or explosions. Keep away from
alkaline materials, acetylene, strong acids, strong bases,
copper compounds. Add 0.1% phenol to gas to prevent
polymerization.
Check Digit Verification of cas no
The CAS Registry Mumber 593-60-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 593-60:
(5*5)+(4*9)+(3*3)+(2*6)+(1*0)=82
82 % 10 = 2
So 593-60-2 is a valid CAS Registry Number.

Radical Carbonyl Propargylation by Dual Catalysis
Huang, Huan-Ming,Bellotti, Peter,Daniliuc, Constantin G.,Glorius, Frank

Carbonyl propargylation has been established as a valuable tool in the realm of carbon–carbon bond forming reactions. The 1,3-enyne moiety has been recognized as an alternative pronucleophile in the above transformation through an ionic mechanism. Herein, we report for the first time, the radical carbonyl propargylation through dual chromium/photoredox catalysis. A library of valuable homopropargylic alcohols bearing all-carbon quaternary centers could be obtained by a catalytic radical three-component coupling of 1,3-enynes, aldehydes and suitable radical precursors (41 examples). This redox-neutral multi-component reaction occurs under very mild conditions and shows high functional group tolerance. Remarkably, bench-stable, non-toxic, and inexpensive CrCl3 could be employed as a chromium source. Preliminary mechanistic investigations suggest a radical-polar crossover mechanism, which offers a complementary and novel approach towards the preparation of valuable synthetic architectures from simple chemicals.
