Thermal reaction of aroylketenes 2 with cyclic enol ethers such as 2,3- dihydrofuran (A), 2,3-dihydropyran (B), 1-trimethylsilyloxycyclopentene (C), 1-trimethylsilyloxycyclohexene (D), 3-trimethylsilyloxyindene (E), and 4- trimethylsilyloxy-1,2-dihydronaphalene (F) was carried out to investigate the reactivity of 2 with these olefins. The main reaction was Michael-type addition to give the 1,3-diketones 3 and 9, and the 1,3,5-triketones 13, 15, 18, and 20, depending on the olefins used. The addition of the olefins was facilitated by introduction of a nitro or chloro group into the aryl part of 2 and was profoundly retarded by steric hindrance of the olefins.

In order to investigate the anti-oxidant properties on lubricant oils, 5,6-dihydro-8-phenyl[1,2]dithiolo[1,5-b]naphtho[2,1-d][1,2]dithiole-10-SIV and a number of phenyl substituted derivatives have been synthesized by cyclization with P2/
