PREPARATION OF FLUOROALKANE FROM ALKENEPURPOSE: To obtain fluorinated alkanes useful as a foaming agent, a solvent and a cooling medium by reacting alkenes not perhalogenated at the double- bonded carbons and carbon adsorbing and containing fluorine therein in the absence of a catalyst.SUU SAN TAN...
Synthesis, structures, and reactivity of (R6-acen)ZrR′2 and (R6-acen)Zr(R′)+ complexes (R = H, F; R′ = CH2CMe3, CH2Ph) The synthesis, structures, and reactivity of neutral and cationic Zr(IV) alkyl complexes incorporating acen and hexafluoroacen ligands are described. Alkane el...
is between about 0.7 and 1.5 moles of hydrogen halide per mole of active species. The use of excess hydrogen halide may result in the halogenation of compounds in the hydrocarbon stream other than the active unsaturated species and the preparation of 1,2-dihaloalkanes from the active species....
