Safe, simple and efficient approach to bicyclic phosphines based on magnesium phosphide
Abstract
Reactions of cycloocta-1,5-diene and (R)-limonene with PH3 result in formation of bicyclic secondary phosphines, applicable in the synthesis of terniary phosphine ligands. To avoid the problems of storage and handling of PH3, we suggest the use of Mg3P2 in its available form, Magtoxin®, as a phosphine source. Higher yields of the target products were confirmed by DFT modeling of the multistep free-radical addition of PH3 to cyclic dienes with the assumption of intramolecular hydrogen transfer at a rate-limiting step.
