General Description

1,1,1-Trifluorobutane, also known by its IUPAC name of butane, 1,1,1-trifluoro-, is a type of organic compound within the hydrofluorocarbons category. It contains three fluorine atoms attached to a carbon atom, along with a carbon chain, creating its distinct structure. 1,1,1-TRIFLUOROBUTANE can exist as a colorless, odorless gas at room temperature and plays a role in various industries. It is commonly used in refrigeration due to its excellent cooling properties, electrical insulation for its non-conductivity attributes, and in the manufacturing of semiconductors. Precautions must take place when handling 1,1,1-trifluorobutane as it can act as a simple asphyxiant and may also have environmental effects due to its potential to contribute to global warming.

Transition state for alkyl group hydrogenation on Pt(111)

Substituent effects have been used to probe the characteristics of the transition state to hydrogenation of alkyl groups on the Pt(111) surface. Eight different alkyl and fluoroalkyl groups have been formed on the Pt(111) surface by dissociative adsorption of their respective alkyl and fluoroalkyl iodides. Coadsorption of hydrogen and alkyl groups, followed by heating of the surface, results in hydrogenation of the alkyl groups to form alkanes, which then desorb into the gas phase. Temperature-programmed reaction spectroscopy was used to measure the barriers to hydrogenation, ΔEH≠, which are dependent on the size of the alkyl group (polarizability) and the degree of fluorination (field effect). This example is one of only two surface reactions for which the influence of the substituents on ΔE H? has been correlated with both the field and the polarizability substituent constants of the alkyl groups in the form of a linear free energy relationship. Increasing both the field and the polarizability constants of the alkyl groups increases the value of ΔEH ?. The substituent effects are quantified by a field reaction constant of ρF = 27 ± 4 kJ/mol and a polarizability reaction constant of ρα = 19 ± 3 kJ/mol. These suggest that the transition state for hydrogenation is slightly cationic with respect to the alkyl group on the Pt(111) surface, RC + H ←{RC δ+ ...H)?.

A novel trifluoromethylation method of saturated organic halides

Treatment of methyl chlorodifluoroacetate with aliphatic halides in the presence of equivalent ammount of potassium fluoride, copper iodide and cadmium iodide at 120°C in HMPA for 8 h gave the corresponding trifluoromethyl derivatives in moderate yields.
