Organometallic compounds derived from thioamides RCH2CSN(R3)2 condense normally with aldehydes and saturated ketones.Condensation with 4-t-butylcyclohexanone leads predominantly to equatorial attack by the organometallic compound.These results suggest that the organometallic structure is RCH=C(SM)N(R3)2.The stereoselectivity of the reaction with benzaldehyde depends on R and R3; a mechanism for the formation of β-hydroxythioamides is discussed.
