Zeitschriftenaufsatz / Fach: Chemie
The reaction of chloromethylenephosphines ClP:CRSiMe3 (R = SiMe3, Ph) with the inverse cyclopropylidenephosphines I (R1 = CMe3, adamantyl) leads to the formation of the title compds. II as a new class of cross-conjugated phosphapolyenes. The structure of II (R1 = CMe3, R = SiMe3) was confirmed by x-ray crystallog.
