A novel bis-CF-substituted diazaphosphole was synthesized selectively from hexafluoro-2-butyne and a 3-1,2,3,4-triazaphosphole derivative. The [4+2] cycloaddition and subsequent cycloreversion reaction under elimination of pivaloyl nitrile affords the product in high yield. The heterocycle coordinates the phosphorus atom to a W(CO)-fragment and shows stronger π-accepting properties than the triazaphosphole.
一种新型的双-CF取代二氮杂磷环戊二烯是由六氟-2-丁炔和一种3-1,2,3,4-三氮杂磷环戊二烯衍生物选择性合成的。在消除新戊腈的条件下,[4+2]环加成反应及随后的环化逆转反应能以高产率得到产物。该杂环将磷原子与一个W(CO)片段配位,并且比三氮杂磷环戊二烯表现出更强的π-接受性质。
