Abstract:
The molecule of the title compound, C(32)H(48)O(4)P(2)S(2), has 2 symmetry, the mid-point of the S-S bond being located on a twofold rotation axis. The two tetra-hedral P units are linked by a S-S bond with a P-S-S-P torsion angle is 131.19 (6)°. The dihedral angle between two phenyl rings is 12.66 (13)°. The cyclo-hexane ring of the menthoxyl group displays a chair conformation. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.

The reaction begins with the nucleophilic addition between a phosphorus ylide and the carbonyl compound. Due to its carbanionic character, phosphorus ylide acts as a strong nucleophile and attacks the electrophilic carbonyl group. This generates a charge-separated dipolar intermediate called betaine. The negatively charged oxygen atom and...
