Synthesis of new C60 based phosphines

Two series of new phosphine derivatives based on C60 protected by borane have been synthesized and characterized. These phosphines were used for two preliminary complexation trials with [RhCl(COD)]2 and [Re(S3CPh)2(S2CPh)] to afford, respectively, the corresponding complexes [RhCl(COD)(PRPh2)] and [Re(S2CPh)3(PRPh2)].
