A study has been made of the condensations between N-acyl-N′,N′-disubstituted thioureas and α-halogeno ketones [reaction (I)], and between N,N-disubstituted thioureas and 2-bromo-1,3-diketones [reaction (II)]. The mechanistic details were elucidated by using substrates with pairs of (almost) equally reactive but spectrometrically distinguishable acyl groups, e.g., CH3CO and CD3CO. In the presence of
