Procedure

The procedure was analogous to Example 6. 26.6 g (0.096 mol) of tin(II) bromide and 9.6 g (0.096 mol) of acetylacetone were reacted with 7.6 g (0.096 mol) of acetyl chloride in 200 ml of diethyl ether and the reaction solution was concentrated to give 36.4 g (96% of theory) of 1-methylbut-1-en-3-onyltin dibromide chloride (Br2 ClSn--C(CH3)=CH--CO--CH3) melting at 112°-115° C.
