Atmospheric lifetimes and global warming potentials of CF 3CH2CH2OH and CF3(CH 2)2CH2OH

A comprehensive study of several atmospheric degradation routes for two hydrofluoroalcohols, CF3(CH2)x=1,2CH 2OH, is presented. The gas-phase kinetics of their reactions with hydroxyl radicals (OH) and chlorine (Cl) atoms are investigated by absolute and relative techniques, respectively. The room-temperature rate coefficients (±σ, in cm3 molecule-1 s-1) k OH and kCl, are respectively (9.7±1.1)× 10-13 and (1.60±0.45)× 10-11 for CF 3CH2CH2OH, and (2.62±0.32)× 10-12 and (8.71±0.24)× 10-11 for CF 3(CH2)2CH2OH. Average lifetimes of CF3CH2CH2OH and CF3(CH 2)2CH2OH due to the OH and Cl reactions are estimated to be 12 and 4 days, and greater than 20 and 4 years, respectively. Also, the IR and UV absorption cross sections of CF3(CH 2)x=1,2CH2OH are determined in the spectral ranges of 500-4000 cm-1 and 200-310 nm. Photolysis of CF 3(CH2)x=1,2CH2OH in the actinic region (I≥290 nm) is negligible compared to their homogeneous removal. Additionally, computational IR spectra are consistent with the experimental ones, thus giving high confidence in the obtained results. The lifetimes of CF3(CH2)x=1,2CH2OH and IR spectra reported herein allow the calculation of the direct global warming potential of these hydrofluoroalcohols. The contribution of CF3(CH 2)xCH2OH to radiative forcing of climate change will be negligible.

Highly selective hydroformylation of 3,3,3-trifluoropropene to 4,4,4-trifluorobutanal using Rh/Xantphos catalyst

Synthesis of 4,4,4-trifluorobutanal by Rh-catalyzed hydroformylation of 3,3,3-trifluoropropene with bis(4,5-diphenylphosphino)xanthene as a ligand was investigated. The uses of [Rh(OH)(cod)]2 (cod = 1,5-cyclooctadinene) and dimethylformamide in CO/H2 = 75/25 mixed gas under atmospheric pressure at 80 C for 15 h provided the highest aldehyde yield 90%. The molar ratio of linear aldehyde (4,4,4-trifluorobutanal) to branched aldehyde (3,3,3-trifluoro-2-methylpropanal) was 99/1. The successive addition of dimethylformamide solution of 3,3,3-trifluoropropene under atmospheric pressure revealed that 4,4,4-trifluorobutanal formation increased linearly with the reaction time and the total turnover number reached 500 after 10 h retaining 99% selectivity of 4,4,4-trifluorobutanal at 80 C.

Method for synthesizing 4,4,4-trifluorobutanol

The invention discloses a method for synthesizing 4,4,4-trifluorobutanol, and belongs to the technical field of organic synthesis. The method comprises the following steps: using 3-halo-1,1,1-trifluoropropane as a raw material to prepare 4,4,4-trifluorobutyraldehyde by two methods of a Grignard method and a DMF step method or a metal lithium/DMF one-pot method, respectively; then, reducing with borohydride salt to obtain 4,4,4-trifluorobutanol, wherein the product is easy to self-decompose and tar; hydrolyzing again to free out the product for purification after adding trimethyl borate or acetonylidene to a reaction system for alcohol exchange, distillation and purification. The method is stable and reliable, successfully performed during amplification in a kilogram scale, and stable in yield.

Rapid access to β-trifluoromethyl-substituted ketones: Harnessing inductive effects in wacker-type oxidations of internal alkenes

We present a practical trifluoromethyl-directed Wacker-type oxidation of internal alkenes that enables rapid access to β-trifluoromethyl-substituted ketones. Allylic trifluoromethyl-substituted alkenes bearing a wide range of functional groups can be oxidized in high yield and regioselectivity. The distance dependence of the regioselectivity was established by systematic variation of the number of methylene units between the double bond and the trifluoromethyl group. The regioselectivity enforced by traditional directing groups could even be reversed by introduction of a competing trifluoromethyl group. Besides being a new powerful synthetic method to prepare fluorinated molecules, this work directly probes the role of inductive effects on nucleopalladation events.
