Avenue to phosphaalkenes from Ph3GePCO

Reactions of Ph3GePCO with KP(t-Bu)2 and Ph3SiCl, or direct reaction with Ph3SiP(t-Bu)2 provides the (Z)- and (E)-isomers of the phosphaalkene (t-Bu2)PC(OSiPh3)P(GePh3) 2, respectively. These isomers interconvert thermally and photochemically, while 2 also undergoes silyl and phosphide exchange with...

Zusammenfassung:	Reactions of Ph3GePCO with KP(t-Bu)2 and Ph3SiCl, or direct reaction with Ph3SiP(t-Bu)2 provides the (Z)- and (E)-isomers of the phosphaalkene (t-Bu2)PC(OSiPh3)P(GePh3) 2, respectively. These isomers interconvert thermally and photochemically, while 2 also undergoes silyl and phosphide exchange with silylphosphines, consistent with a mechanism involving the reversible silylphosphination of Ph3GePCO.
