β¦ Synopsis
The carbon NMR spectra of acetylene-metal pi complexes have been measured for a few examples of Pt(II),l Pt(O),' and COG complexes. Carbon spectra of olefin-silver(I) complexes have been reported.4-6 However, the factors affecting carbon chemical shifts are still the subject of debate. 7 In this communication we report the carbon spectra of acetylene

## Abstract Carbonβ13 NMR chemical shifts are reported for six angular and one linear dichloropyridoquinolines in CDCl~3~. The chemical shift assignments have been made using model compounds, fully coupled spectra, selective proton decoupling and results from lanthanide shift studies. Chlorine subs
The =C chemical shifts of a series of isoflavones having hydroxy, acetoxy, methoxy and methylenedioxy substituents are compared. Some general relationships between substitution patterns and chemical shifts, useful for the identitication of naturally occurring isoflavones, are outlined.
