Chem., 32, 1558 (1967). 10 Another noteworthy observation but not directly related to the above discussion is the presence of a deshielding effect exerted by the 2-phenyl of VIII upon the 3-hydrogen in deuteriochloroform indicating that the 2-phenyl must possess some co-planarity with the entire ring system (e.g., i). 11 Spectra were determined on a Varian A-60 Spectrometer in deuteriochloroform and trifluoroacetic acid with tetramethylsilane as an internal standard at ambient probe temperatures. 12 Multiplicity designated as s, d, t, q and m represents singlet, doublet, triplet, quartet and multiplet, respectively. 13 Melting points were taken on a Mel-Temp capillary melting point apparatus and were corrected. The microanalyses were performed by Midwest Microlab, Inc., Indianapolis, Indiana. 14 F. Krollpfeiffer and H. Schultze, Ber., 56, 1819 (1923). 15 F. Arndt, Ber., 56, 1269 (1923). 16 C. D. Hurd and S.
