✦ Synopsis

OZEANO HMXLIA (Bologna)-ITALY C-13 NMB data for a series of stabilized and unstabilized ylides indicate flattening at the ylidic carbon with respect to the Parent salts. For unst*ilired ylides association between the oarbanionic center and the lithium cation cannot be neglected. Sulfunium yfides are the intermediates in the B/D base-catafysed exchange'

## Abstract ^13^C NMR spectra of six kawa‐pyrones (styryl α‐pyrones) have been assigned. The assignments are based on the splitting pattern in the coupled spectra, comparison of the chemical shifts with those of model compounds and by application of additivity relationships. The ^13^C NMR of styren
