YieldReaction ConditionsOperation in experiment
79% With potassium tert-butylate; In DMF (N,N-dimethyl-formamide); at 5 - 20℃; for 24h;Product distribution / selectivity; 1.13 g of tetraethyl 4,4'-dimethylbiphenyl-alpha,alpha'-diyl-diphosphonate and 1.42 g of 2'-formyl-alpha-phenylstilbene were dissolved in 10 ml of N,N-dimethylformamide. At 5 to 10 C., 0.65 g of potassium tert-butoxide was gradually added to the reaction over 10 minutes. The reaction mixture was then stirred at room temperature for 24 hours. 30 ml of ethanol was then added. The precipitate was recovered by filtration, washed with water and then dried to obtain pale yellow powders. The pale yellow powders were then re-crystallized from toluene, to obtain 0.82 g of pale yellow needle crystals (yield 79%). The melting point thereof was 242.0 to 247.0 C. The elementary analysis of this product resulted in 93.89% carbon (theoretical value as compound 1-82: 94.08%), and 5.81% hydrogen (theoretical value as compound 1-82: 5.92%). In infrared absorption spectrum (KBr tablet), stretching vibration due to aromatic rings was recognized at around 1590 cm-1. In proton nuclear magnetic resonance spectrum (solvent CDCl3, internal standard TMS), ring protons of aromatic rings and alkene protons were recognized at delta=6.9 to 7.8 ppm (42H). In mass spectrum, a molecular ion peak m/z=714 was recognized. From these results, it was confirmed that the compound thus obtained was compound No.1-82

YieldReaction ConditionsOperation in experiment
49% With potassium tert-butylate; In DMF (N,N-dimethyl-formamide); at 5 - 20℃; for 20h;Product distribution / selectivity; 4.54 g of tetraethyl 4,4'-dimethylbiphenyl-alpha,alpha'-diyl-diphosphonate and 2.64 g of 2-methylbenzaldehyde were dissolved in 40 ml of N,N-dimethylformamide. At 5 to 10 C., 2.60 g of potassium tert-butoxide was gradually added to the reaction over 10 minutes. Subsequently, the reaction mixture was stirred at room temperature for 20 hours, and then poured into a mixture consisting of 150 ml of water and 150 ml of ethanol. The precipitate was recovered by filtration, washed with water and then dried to obtain pale yellow crystals. The crystals were re-crystallized from a mixed solvent of toluene and ethanol, to obtain 1.88 g of pale yellow crystals (yield 49%). The elementary analysis of this product resulted in 93.09% carbon (theoretical value as compound2-17: 93.22%), and 6.60% hydrogen (theoretical value as compound 2-17: 6.78%). In infrared absorption spectrum (KBr tablet), stretching vibration due to aromatic rings was recognized at around 1600 cm-1. In mass spectrum, a molecular ion peak m/z=386 was recognized. From these results, it was confirmed that the compound thus obtained was compound No.2-17.
