OXIDATIVE ADDITION OF 2,3,4-BENZOTRITHIEPIN 1-OXIDE TO PLATINUM(0) COMPOUNDS : A CONVENIENT SYNTHETIC ROUTE TO PLATINUM(II) THIOSULFINATO COMPLEXES
1998
Abstract The oxidative addition of 2,3,4-trithiepin 1-oxide 2 to (Ph 3 P) 2 Pt(C 2 H 4 ) 5 gives the platinum(II) thiolato thiosulfinato complex cis -{(Ph 3 P) 2 PtS-S(O)-CH 2 -C 6 H 4 -CH 2 -S 6 . The structure of 2 was established by X-ray structural analysis. 2 crystallizes in the monoclinic space group P 2 1 / c with a = 878.52(10), b = 1263.4(2), c = 936.95(10) pm, β = 117.818(9)°, Z = 4. The 2,3,4-trithiepin 2-oxide 4 reacts with 5 to form the diplatinum(II) thiolato complex 8 . Formally, 1 equiv. SO has been eliminated during this reaction.
