The starting complex [PtCl{(κ2-P,C)P(OC6H4) (OPh)2}SMe2], 3, was prepared by a new method using the reaction of [PtCl2(P(OPh)3)2] with 1 equiv of PtCl2 in x

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 the known 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 [PtCl 2{P(OPh)3}2] yields the fourcoordinate 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-[Pt 2(SePh)4{P(OPh)3}2] (5).
Synthesis and NMR spectroscopy of cyclopalladated tertiary phosphite complexes. X-ray crystal structure of Pd(η5-C5H5)(P(OPh)2(OC6H4))

The paper reports the authors' initial studies on the cyclometalation and characterization of complexes derived from P(OPh)3 and P(OEt)2(OPh), with the latter ligand selected so that after cyclometalation and subsequent transformation (e.g., carbonylation), hydrolysis would readily yield the ortho-substituted phenol. For comparison purposes the authors have also prepared and cyclopalladated P(OEt)2(NMePh), an N-methylaniline analog. In the course of this work, the crystal structure of Pd(η5-C5H5)(P(OPh)2(OC6H4)) was determined and found to contain some interesting features, which are discussed as well.
