Provided are organometallic complexes that can exhibit phosphorescence. One of the novel organometallic complexes is represented by General Formula (G1). In General Formula (G1), R1 represents any of an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms which may have a substituent, and an aralkyl group having 7 to 10 carbon atoms which may have a substituent. In addition, R2 represents any of an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms which may have a substituent, and an aryl group having 6 to 12 carbon atoms which may have a substituent. Further, Ar represents an arylene group having 6 to 13 carbon atoms which may have a substituent. Further, M represents a Group 9 element or a Group 10 element.

Some sterically hindered N-nitrosamides have been prepared using sodium nitrite in aqueous acid solution.Reaction of these N-nitrosamides with 2,4-bis-(4-methoxyphenyl)-1,2,3,4-dithiadiphosphetane-2,4-disulfide (Lawesson's Reagent ) causes thiation of both the carbonyl and the nitroso groups followed by destruction of the nitroso group giving ultimately the corresponding thioamides and amides as the main products.Dihydro-2(3H)-thiophenone is isolated as a by-product when N-nitroso-dihydro-2(3H)-pyrrolidinone is reacted with LR.A mechanism for its formation is postulated.Thiation of the sterically hindered amides yields the thioamide as rotamers which in two cases could be separated by column chromatography.Ames test has been performed for some of the compounds.
