 Title    Bis(triphenylphosphoniumyIidyl)phosphane Bis(triphenylphosphoniumylidyl)phosphanes  
 Abstract    Bis(ylidyl)phosphanes can be prepared from ylides and dichlorophosphanes or from bis-(ylidyl)phosphenium chlorides and organolithium compounds. By substituting in bis(ylidyl)-phosphenium chlorides the chloride ion for more basic anions, a large variety o f bis(ylidyl)-phosphanes is accessible. They can be protonated at the ylidic carbon atoms, but alkylated and oxidized at the central phosphorus atom. A s shown by 3IP NM R in solution and by X-ray investigation of the crystal, the lone pair at the tervalent phosphorus is generally oriented synperiplanar to both phosphonio groups.
