Abstract
Recently, Jensen and Petrakis published a potentially useful chemical shift-structure correlation chart for 13c nmr. The chart, though reasonably comprehensive, neglects Allenic type carbons. We feel that this is an unfortunate omission since (1) Allenic carbons of the type =c= give chemical shifts in the region generally attributed to carbonyl carbons, and (2) =ch2 and =ch Allenic carbon resonances appear in the same spectral region as do the triply bonded carbons in alkynes.
