| Abstract: | The new donor functionalized methylthio-phosphabenzene 3 was synthesized by reaction of the corresponding pyrylium salt with P(SiMe3)3. This compound was characterized crystallographically, showing eight independent molecules in the asymmetric unit. 3 crystallized in the orthorhombic space group Pna21 (no. 33) with cell parameters a=48.3565(8) ?, b=7.64784(7) ?, c=40.8432(4) ?, V=15104.7(3) ?3. This result represents the first crystal structure analysis of a λ3-triaryl-phosphabenzene. |
