The preparation of ((CH3) 2CHS) 2AlCH3 and (t-CaH9S) 2AlCH3 is reported. The reactions of (RS) 2AlCH3 (R= CH3,(CH3) 2CH, t-C4H9) with ketones give aldol condensations leading to the corresponding conjugated ketones, with the acetyl group R-CO-CH3; with other ketones, a mixture of thioacetal and enolthioether is obtained. With aldehydes, a mixture of thioacetal and enolthioether is observed. With olefins there is an addition of two ...
