Starting with the potassium salt of (1), the following reactions in THF were identified: (1) 1+H2 -> fac-^- (2); (2) 1+1,4-Ph2-1,3-butadiene -> ^- (3) + PPh3; (3) 3+4H2 -> ^- (4) + 1,4-Ph2-butane; (4) 4 + 1-hexene -> ^- (5) + hexane; (5) 4 + L -> ^- + H2 (L = CO, PPh3, PMe2Ph); (6) 2 + 1,5-anthracene (A) -> ^- (7) + 0.5 (1,2,3,4-H4A) + PPh3; (7) 4 + 5 C2H4 -> (8) + 3C2H6; (8) 4 + 2A -> 7 + 1,2,3,4-H4A; (9) 7 + 4H2 -> 4 + 1,2,3,4-H4A.Reactions 8 and 9 constitute a catalytic cycle for the hydrogenation of anthracene to 1,2,3,4-tetrahydroanthracene.
