Carboncations also form from an alkyl halide when a Lewis acid catalyst is used. Aluminum chloride is the commonly used Friedel-Crafts alkylation catalyst. Friedel-Crafts alkylation reactions have been reviewed by Roberts and Khalaf ...

Van t Hoff here referred to a lecture in which the twenty-six-year-old Lespieau had introduced the new physical chemistry of van t Hoff, Ostwald, and Arrhenius to colleagues in Friedel s Sorbonne laboratory. Among other things, Lespieau dealt in his paper with a problem posed by van t Hoff having to do with the validity of neglecting the difference in specific heats of water and ice, and Lespieau demonstrated that the term where this difference figures can be finally eliminated. 13 Who was Robert Lespieau ...

Robert A. Friedel. It would be interesting to carry out the work suggested by Dr. Wender. Type analyses of C naphthenes from a coal hydrogenation product have been reported (2) the types analyzed include ethyl-cyclohexane, propylcyclopentanes, dimethylcyclohexanes, gem-trimethyIcyclo-pentanes, other trimethylcyclopentanes, and methyl-ethylcyclopentanes. Some compounds in these classes could be optically active. Comparable analyses of catalytically reformed petroleum would be of considerable interest in trying to ascertain what optically active components are produced in the reforming. 

Robert A. Friedel. What is your interpretation of the fine structure indicated by your EPR spectrum. 

Robert A. Friedel. Can you take an electron micrograph of an organic sample at high magnification—e.g., 50,000 X—and then obtain exactly the same picture on taking a second shot of the same spot It is my impression that the newest equipment with careful techniques can do this, but that with... 

Robert Friedel In your calculations on the C-H-N system have you considered species related to hydrazine ... 

Robert A. Friedel To Dr. Sharkey s remarks on mass spectroscopy I would like to add a few pertinent comments on other types of spectroscopy which would be applicable to the study of species obtained from coal subjected to plasma, laser irradiation, and similar high energy processes.

Roberts and Day (172) investigated the polymerization of a- and /S-pinenes with Friedel-Crafts halides as catalysts in toluene at 40—45° C. Under comparable conditions the / isomer polymerized much more vigorously than the a, and it gave higher conversions and higher softening products.
