| Popis: | Synthesis, spectroscopic data and X-ray structure determination of a novel phosphaalkene, Me5C5-P=C(SiMe3)2 1, are reported. It is shown by dynamic 1H-NMR spectroscopy that 1 exhibits thermal E/Z-isomerization of the double bond at ambient temperature. Reactions of 1 involve electrophilic attack of the π-system with hard (H+) and soft (Ag+) Lewis-acids, and an unusual cleavage of a PC-single bond on reaction with metal complexes (MeCN)3M(CO)3, (M = Mo, W). |
