  Reactions of 5,6,11,12-tetradehydrodibenzo[a,e]cyclooctene with 1,2-C6H4(SiMe2)2Pt(PPh3)2 and Pt(CH2-CH2) (PPh3)2. x-ray structure determination of resulting double silylated compounds and platinum-alkyne complexes

  摘要：

  The platinum complex of 5,6,11,12-tetradehydrodibenzo[a,e]cyclooctene (1), [(Ph3P)(2)Pt](2)[1], was synthesized quantitatively by the reaction of 1 with Pt(CH2=CH2)(PPh3)(2). The reaction of 1 with 1,2-C6H4(SiMe2)(2)Pt(PPh3)(2) gave 5,5,10,10,15,15,20,20-octamethyl- 5,10,15,20-tetrahydro-5,10,15,20-tetrasiladibenzo[b,n]tetraphenylene ([C6H4(SiMe2)(2)](2)(C16H8)) and [(Ph3P)(2)Pt][C6H4(SiMe2)(2)-C16H8] (C6H4(SiMe2)(2)C16H8 = 5,5,16,16-tetramethyl-5,16-dihydro-10,11-didehydro-5,16-disiladibenzo[a,e]naphtho[c]cyclooctene) as well as [(Ph3P)(2)Pt](2)[1]. The central eight-membered ring of [C6H4(SiMe2)(2)](2)(C16H8) has a typical tub-shaped structure, while that of [(Ph3P)(2)Pt](2)[1] is much less folded. The structure of [(Ph3P)(2)Pt][C6H4(SiMe2)(2)C16H8] lies between those of [C6H4(SiMe2)(2)](2)(C16H8) and [(Ph3P)(2)Pt](2)[1].
