As demonstrated by Laszlo Kürti′s lab, ketomalonate oxime O-sulfonates act as doubly N-electrophilic linchpin reagents towards strong C-nucleophiles such as alkyl- and arylmetals (e.g., Grignard reagents). Thus, symmetrical dialkyl- as well as diarylamines may be directly prepared at low tempretatures and in the absence of transition metal catalysts. Other ketomalonate oxime O-sulfonates include 902918, 902624 and 902748.
