Procedure: 28.61 Grams of 1,9-dibromononane and 52.46 g of triphenylphosphine were weighed out and placed in a 500-mL three-necked flask. These compounds were dissolved in 100 mL of N-methylpyrrolidone. This solution was stirred at 80° C. for 5 hours and the resultant reaction mixture was cooled to room temperature. Thereafter, the reaction mixture was poured into 500 mL of ethyl acetate kept being sufficiently stirred. The solid precipitated was collected by suction filtration and washed with 50 mL of ethyl acetate twice. The solid obtained was placed on a Petri dish and dried at room temperature under vacuum until the mass of the solid became constant. As a result, nonamethylenebis(triphenylphosphonium)dibromide was obtained as a white solid in an amount of 73 g (yield: 90%). placed in a 500-mL three-necked flask the resultant reaction mixture was cooled to room temperature kept being sufficiently stirred The solid precipitated was collected by suction filtration washed with 50 mL of ethyl acetate twice The solid obtained dried at room temperature under vacuum until the mass of the solid

Procedure: 103 g (0.36 mol) 1,9-dibromononane is stirred at 120° C. and a solution of 11.8 g (0.045 mol) triphenylphosphine in 120 ml toluene is added within 8 hours. After a further 10 hours at 120° C. it is allowed to cool, the supernatant is decanted and the viscous residue is stirred twice with isohexane at 60° C. After drying on a rotary evaporator in a stream of nitrogen 22.4 g (91%) 65 was obtained as a nearly colourless resin. to cool the supernatant is decanted After drying on a rotary evaporator in a stream of nitrogen 22.4 g (91%) 65 was obtained as a nearly colourless resin
