Starting from a chiral resolution of 2-ethylhexanoic acid followed by conversions of functional groups without interfering with the enantiopurity, we have successfully introduced an enantiopure 2-ethylhexyl group on to dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT) via a Negishi-coupling reaction to synthesize 2-(R)-(2-ethylhexyl)- and 2-(S)-(2-ethylhexyl)-DNTT (R- and S-EH-DNTT, respectively).

This paper describes the construction and operation of the 1,090MW gas-steam combined cycle power plant, one of the largest of its kind in the world. The plant consists of two trains, each of which combines three sets of gas turbines and heat recovery steam generators with one set of steam turbines. A gas turbine burns gasified LNG as fuel with gas firing temperature of 1,154°C at the base load operation, the highest temperature now in service, with a newly developed low NOx premixing type combustor system and generates 133MW each at maximum. The construction of the plant was started in March, 1982 and the first train, namely, one half of 1,090MW has been in commercial operation since December, 1984 with a very high average thermal efficiency of 44.1% (H.H.V.). The 1,090MW total plant is scheduled to complete in October, 1985 when the second train starts commercial operation.
