The ultraviolet spectra are reported of a series of 9-alkylphenanthrenes. The bathochromic shifts relative to phenanthrene of the longest-wavelength (α) band are not explicable in terms of hyperconjugation. It is suggested that the band envelope is influenced by the rotameric forms of the alkyl substituents.

Deuteratedorganiccompounds have become increasingly important in many areas; however, it remains challenging to install deuterium site-selectively to unactivated aliphatic positions with control of the degree of deuteration. Here, we report a Cu-catalyzed degree-controlled deacylative deuteration of diverse alkyl groups with the methylketone (acetyl) moiety as a traceless activating group. The use
