Yam and co-workers reported the first luminescent study of 4-coordinate gold(I) phosphine complexes, [Au(PAP)2]X (PAP = l,8-bis(diphenylphos-phino)naphthalene, 4-methyl-l,8-bis(diphenylphosphino)naphthalene X = Cl, PF6) in 2000 [28]. The complexes were shown to exhibit orange-red photoluminescence both in the solid state and in dichloromethane, and the emission origin was attributed to the triplet state derived from a [a -> 77- (naphthyl)] IL transition. The PF6 salt of the complexes were also employed as an emissive layer in the fabrication of OLEDs. 

To our knowledge, no such effective optical resolution by inclusion formation with an optically active channel-type host compound has been reported so far. 1,2-Bis(2-methyl-1-naphthyl)-l,2-bis(2,4,6-trimethylphenyl)ethane (80) yields a 1 1 crystal inclusion with (+)-a-pinene, but successive recrystallization of 80 from (-i-)-a-pinene gives only a partial optical resolution... 

Other evidence was reported by Tsukahara and collaborators from the disproportionation reaction of the radical cation of the optically active bis-viologens, (S)-l-(l-naphthyl ethyl)carbamoyln methyl-r-(4-(4-(l-naphthyl ethyl)carbamoyl methyl-pyridinio)pyridinio-4,4 -bi pyridinium tetra chloride, NBVPR, 1-phenyl analog, PBVPR, and 1-cyclohexylethyl analog CHBVPR (see Scheme 28) [70].

Benzoin, tetraphenylethanediol, hydrazobenzene and 1,2-diphenyl-1,2-ethanedione bishydrazone are oxidized by methyl bis(l-naphthyl)bismuthi-nate to benzil, benzophenone, azobenzene and diphenylacetylene, respectively [88CL2021] (Section 5.2.4). Amides, thioamides, ureas and thioureas are A-acylated in good yield with acetic acid in the presence of the bismuthi-nate at room temperature [90CL1651] (Scheme 3.11). 

DCA sensitisation of tri-1-naphthyl phosphate or di-l-naphthyl methyl-phosphonate results in formation of l,r-binaphthyl. The reaction occurs only in compounds with at least two naphthyl substituents linked by an 0-P(0)-0 chain. Reaction involves intramolecular face-to-face dimerisation of the two naphthyl units within the radical cation (445), followed by elimination of the 1,1 -binaphthyl radical cation, which is subsequently reduced by the DCA radical anion. In a related reaction DCA-sensitisation of bis(3,4-methylenedioxy-phenyl) methylphosphonate in acetonitrile gives 2-(3,4-methylenedioxyphenyl)-4,5-methylenedioxyphenyl methylphosphonate whereas direct irradiation in methanol gives bis(3,4-methylenedioxy)biphenyl as an additional product.
