Lewis base mediated dismutation of trichlorosilanewz
An abnormal N-heterocyclic carbene (aNHC) has been used as a Lewis base to initiate dismutation of trichlorosilane. This report presents the reactivity differences of a normal N-heterocyclic carbene (NHC) versus aNHCwith heavier group 14 elements. Three novel compounds (NHC)2 SiCl2H2 (2), aNHC SiCl2H2 (3), and aNHC GeCl2 (4) have been synthesized and characterized by single crystal X-ray analys...

متن کاملLewis base mediated autoionization of GeCl2 and SnCl2.
Cationic and anionic species of heavier low-valent group 14 elements are intriguing targets in main group chemistry due to their synthetic potential and industrial applications. In the present study, we describe the synthesis of cationic (MCl(+)) and anionic (MCl(3)(-)) species of heavier low-valent group 14 elements of germanium(II) and tin(II) by using the substituted Schiff base 2,6-diacetyl...
متن کاملRecent progress in Lewis acid–Lewis base bifunctional asymmetric catalysis*
Two enantioselective cyanation reactions, the Strecker reaction of ketoimines and the Reissert reaction of pyridine derivatives, promoted by Lewis acid–Lewis base bifunctional asymmetric catalysts are described.
متن کاملLewis base mediated halogenation/semipinacol rearrangement of diazo compounds: new access to α-halo-quaternary ketones.
A novel halogenation/semipinacol rearrangement of α-diazo alcohol catalyzed by Lewis base has been developed through a carbene-free mechanism. This semipinacol transposition, initiated by an electrophilic halogenation (X = Cl(+), Br(+), and I(+)) of diazo carbon event, furnished a convenient synthetic route for the efficient synthesis of α-halo-quaternary ketones under mild conditions.
