Popis:	The deprotonation around −70°C of the ketones RCH 2 COCH 3 or R 2 CHCOCH 3 by Et 2 NLi in the mixture HMPT/benzene/ether gives the enolates RCH 2 C(OLi)CH 2 or R 2 CHC(OLi)CH 2 . The condensation of the latter with different aldehydes or ketones around −70°C lead to the expected β-ketols or .
