FT-IR and MAS NMR analysis of montmorillonite K10 supported MF2 reagents and their activity as catalysis /

ZnF2, CdF2, and CUF2 have been adsorbed onto the surface of montmorillonite K10, and the infrared and 19F, 27 AI, and 29Si MAS NMR spectra of the reagents over a range of loadings have been obtained. CUF2 was observed to attack the Si02 layer and form the complex CuSiF6, Zn F2 tends to attack the aluminium oxide layer, in which Zn isomorphously replaces AI, and forms AIF3 and AIF4 - complexes. All the spectroscopic evidence ruled out the formation of any AI-F and/or Si-F free species as CdF2 is adsorbed on the surface of montmorillonite K10. The reactivity of MF2-K10 reagents towards Friedel-Crafts benzylation of benzene with benzyl chloride varied from one reagent to another. ZnF2-K10 was observed to be the most reactive and CUF2 was the least reactive.

Article - "Fonthill Woman Among 21 Pilots in Welland - Florida Air race", 1953

An article in The St. Catharines Standard that discusses the upcoming sixth all-women's international air race from Welland, Ontario to New Smyrna Beach, Florida. Mrs. Rungeling will be accompanied by Beverly Belfry of St. Catharines and wife of a Thompson Products executive. Thompson Products is also sponsoring Mrs. Rungeling's flight and a representative, Mr. Stauffer, of Thompson Products, states "It is encouraging to see the international air race grow as it has done...This year's list of 21 probable entries compares with eight in last year's race".
