Facile cleavage of a phenyl group from SbPh3 by dirhenium carbonyl complexes

“…The Re-Sb distance is similar to that found in compounds 4 and 5, Re(1)-Sb(1) = 2.7124(3) Å . The Re-C distance to the phenyl ring, Re(1)-C(15) = 2.226(4) Å , is very similar to the Re-C distance found in 4 and the compound Cp * Re(CO) 2 (I)Ph, [10].…”

“…The Re-Sb distance is slightly shorter, Re(2)-Sb(2) = 2.7329(4) Å , than those of the bridging SbPh 2 ligand, but it is longer than the Re-Sb bond distance to the SbPh 3 ligand in 12, Re-Sb = 2.671(1) Å [9]. The Re-C distance to the phenyl ring, Re(1)-C(1) = 2.228(5) Å , is only slightly longer than the Re-C distance to the phenyl ring in the compound (C 5 Me 5 )Re(CO) 2 I(Ph), 2.191(5) Å [10].…”

“…Compound 4 was also the major product obtained from the reaction of SbPh 3 with Re 2 (CO) 10 in the presence of UV-Vis irradiation, but the yield was much lower, 34% yield. In addition to 4, three minor products were obtained from this reaction, see Scheme 3.…”

“…It has been shown that a phenyl group is readily cleaved from SbPh 3 in its reactions with the rhenium carbonyl complexes 1 and Re 2 (CO) 10 . The novel r-phenyl complex 4 was formed by insertion of a rhenium atom into the Sb-C(phenyl) bond.…”

“…Leong et al have shown that phenyl groups can also be cleaved from SbPh 3 in its reactions with triosmium and triruthenium carbonyl complexes [4]. Because of the similarities between SbPh 3 and HSnPh 3 , we decided to examine the reactions of SbPh 3 with 1 and also with Re 2 (CO) 10 under conditions of UV-Vis irradiation. These results are reported here.…”
