primary or secondary amines. The reaction with ambident nucleophiles such as amino alcohols was highly selective and took place exclusively at the amino group despite the presence of the alcohol functionality. In parallel to the reaction paths for simple amines, amino alcohols were converted into hydroxysulfinyl amides when the reaction was catalyzed by Pd-xantphos, while Pd(PPh3)4 catalyst afforded cyclic
