Various reducing agents were tested to try and find a new way to synthesize the diphosphene DmpP=PDmp (Dmp = 2,6-dimesitylphenyl). The reducing agents tested were an organosilicon-based compound, 1-methyl-3,6-bis(trimethylsilyl)-1,4-cyclohexadiene (MBTCD), 3,6-bis(trimethylsilyl)1,4-cyclohexadiene (BTCD), and 1,3,1’,3’-tetraethyl-bis(2,2’-imidazolidine). Through the use of dimesitylphenyl phosphorous dichloride (DmpPCl2), it is thought that the chemistry exhibited by these reducing agents on similar compounds could be applied to compounds with PCl2 groups, such as DmpPCl2, in the hopes of creating the diphosphene DmpP=PDmp.
