Platinum complexes of aromatic selenolates
Abstract
Several synthetic methods are used to prepare naphthalene-based aromatic 1,2-diselenoles. A new one-pot synthesis starting from naphthalene is used to produce theknown compound naphtho[1,8-c,d][1,2]diselenole (Se2naph).Friedel–Crafts alkylation is used on Se2naph to substitute either one tert-butyl group to form 2-tert-butylnaphtho[1,8-c,d][1,2]diselenole (mt-Se2naph) or two tert-butyl groups to form 2,7-di-tert-butylnaphtho[1,8-c,d][1,2]diselenole (dt-Se2naph). Bromination of mt-Se2naph results in dibromination of the naphthalene ring, rather than reaction at selenium, to give 4,7-dibromo-2-tert-butylnaphtho[1,8-c,d][1,2]diselenole (mt-Se2naphBr2). Reduction of the Se–Se bond in Se2naph, mt-Se2naph, dibenzo[c,e][1,2]diselenine (dibenzSe2), or diphenyl diselenide (Se2Ph2) with LiBEt3 H, followed by in-situ addition of [PtCl2{P(OPh)3}2] yields the four-coordinate mono- and dinuclear platinum(II) bis(phosphite) complexes [Pt(Se2naph){P(OPh)3}2] ( 1 ), [Pt(mt-Se2naph){P(OPh)3}2] ( 2 ), [Pt2(dibenzSe2)2{P(OPh)3}2] ( 3 ), cis-[Pt(SePh)2{P(OPh)3}2] ( 4 ), and trans-[Pt2(SePh)4{P(OPh)3}2] ( 5 ).
