n-Pentyloxybenzene (Ia) and P4S10 (in a molar ratio of 10:1) were stirred for six hours at 150° C. under anhydrous conditions. The mixture was cooled, toluene was added, and the reaction flask was left for two days at 5° C. The resulting precipitate was recovered by filtration, washed with anhydrous ether and dried. The yield of product was 46% of theory; after recrystallization from chloroform/petroleum ether it melted at 144°-6° C. Its solubility in tetrahydrofuran was found to be 5 gms/100 ml at room temperature.
