1133tetrachloorpropyn

1133tetrachloorpropyn is the designation given to an organochlorine compound that would derive from a propyn skeleton with four chlorine substituents at the 1,1,3,3 positions. The name suggests a three-carbon chain containing a carbon–carbon triple bond with chlorines replacing hydrogens at C1 (two chlorines) and C3 (two chlorines).

In IUPAC terms this combination is problematic because the terminal carbon in a propyn unit bears only one hydrogen, making a 3,3-dichloro substitution geometrically unlikely. Consequently, the exact structure implied by the name is ambiguous and not clearly supported by standard databases or literature references. The name may reflect a nonstandard or non-IUPAC formulation, or it may be a mistyped or fictional label.

There is no widely cited, experimentally validated compound with this exact name in major chemical databases. If such a compound were to exist, it would belong to the class of polyhalogenated alkynes, which are typically highly reactive and potentially hazardous. Handling would require specialized facilities, strict safety protocols, and regulatory oversight due to the corrosive and toxic nature of chlorinated organics and the energetic characteristics of alkynes.
