Characteristic Reactions and Properties of <i>C</i>-Apical <i>O</i>-Equatorial (<i>O-cis</i>) Spirophosphoranes: Effect of the σ*<sub>P</sub><sub>-</sub><sub>O</sub> Orbital in the Equatorial Plane and Isolation of a Hexacoordinate Oxaphosphetane as an Intermediate of the Wittig Type Reaction of 10-P-5 Phosphoranes
Novel spirophosphoranes (O-cis) that exhibit reversed apicophilicity having an apicalcarbon-equatorialoxygen array in a five-membered ring showed enhanced reactivity toward nucleophiles such as n-Bu(4)N(+)F(-) or MeLi in comparison with the corresponding stable isomeric spirophosphoranes (O-trans) having an apical oxygen-equatorial carbon configuration. The enhanced reactivity of the O-cis isomer
