The W(CO)5 and Fe(CO)4 complexes of the bicyclic phosphirane 3,5,6,6-tetraphenyl-1-phospha-2-thiabicyclo[3.1.0]hex-3-ene undergo a thermal 2-phenylphosphirane --> dihydrophosphaisoindole ring expansion, while the free phosphirane suffers both a [2 + 1] cycloreversion and a fragmentation yielding a butadienyl sulfide.
双环膦烷3,5,6,6-四苯基-1-膦-2-噻二环[3.1.0]己-3-烯的W(CO)5和Fe(CO)4配合物经历热2-苯基膦烷->二氢磷基异吲哚环膨胀,而游离磷杂环戊烷同时经历[2 +1]环还原和断裂,产生丁二烯硫醚。
