Reaction Conditions

Reaction Steps

Over a period of 0.5 hour 9.25 g (0.025 mol) of (3-bromopropyl) tripropyltin was added to 25 ml of 3-dimethylaminopropyl amine at room temperature. The mixture was stirred for 1 hour at 60° C. Under cooling 75 ml of diethylether and 60 ml of a 15% aqueous solution of sodium bicarbonate were added. After stirring for 0.5 hour the organic phase was separated, dried and evaporated in vacuo. Distillation gave 7.5 g (77%) of Pr3Sn(CH2)3NH(CH2)3NMe2 ; b.p. 113°-114° C./0.1 mm Hg, nD20 =1.4855.
