Coordination chemistry of benzene, toluene, cyclohexadienes, cyclohexene, and cyclohexane on Pt(100)
The surface chemistry of benzene, toluene, cyclohexane, cyclohexene, and cyclohexadienes on Pt(100) is described. Benzene chemisorption was largely molecular although H-D exchange between chemisorbed C/sub 6/H/sub 6/ and C/sub 6/D/sub 6/ was observed at temperatures of 100/sup 0/C and above. Toluene chemisorbed with bond breaking to give Pt-(100)-benzyl. This benzyl species (C/sub 6/D/sub 5/CD/sub 2/) underwent H-D exchange with chemisorbed hydrogen. Exchange was more facile at the CH/sub 2/ site than at aromatic C-H sites. Cyclohexane, cyclohexene, and cyclohexadienes chemisorbed on Pt(100) to form benzene with the expected relative ease of dehydrogenation of cyclohexadienes greater than or equal to cyclohexene > cyclohexane.
