摘要：

The choice of starting compound for the synthesis of the unstabilized phosphaalkynes 3 has proved to be the (dichloroalkyl)phosphanes 2. They were formed by the reduction of the phosphonates 1 with AlHCl2 and dehydrohalogenized over hot K2CO3 (230-350-degrees-C) in the gas phase. The simple phosphaalkynes 3 are stable in THF at room temperature also-who would have expected that! R = H, Me, Et, nBu, Me3Si. [GRAPHICS]
