  2. Buchner ring expansion - Wikipedia

    en.wikipedia.org/wiki/Buchner_ring_expansion

    The Buchner ring expansion is a two-step organic C-C bond forming reaction used to access 7-membered rings. The first step involves formation of a carbene from ethyl diazoacetate , which cyclopropanates an aromatic ring.

    The ASEBA was created by Thomas Achenbach in 1966 as a response to the Diagnostic and Statistical Manual of Mental Disorders (DSM-I). [3] This first edition of the DSM contained information on only 60 disorders; the only two childhood disorders considered were Adjustment Reaction of Childhood and Schizophrenic Reaction, Childhood Type.

    The Child Behavior Checklist (CBCL) is a widely used caregiver report form identifying problem behavior in children. [ 1 ] [ 2 ] It is widely used in both research and clinical practice with youths. It has been translated into more than 90 languages, [ 3 ] and normative data are available integrating information from multiple societies.

  5. Cyclopropanation - Wikipedia

    en.wikipedia.org/wiki/Cyclopropanation

    Cyclopropanation is also stereospecific as the addition of carbene and carbenoids to alkenes is a form of a cheletropic reaction, with the addition taking place in a syn manner. For example, dibromocarbene and cis -2-butene yield cis -2,3-dimethyl-1,1-dibromocyclopropane, whereas the trans isomer exclusively yields the trans cyclopropane.

  9. Metal-catalyzed cyclopropanations - Wikipedia

    en.wikipedia.org/wiki/Metal-catalyzed_cyclopropa...

    Definitive mechanistic studies of rhodium-catalyzed cyclopropanation are lacking. However, the mechanism has been rationalized based on product distribution and stereoselectivity. [ 4 ] Attack of the diazo compound on the metal center generates a zwitterionic metal alkyl complex, which expels nitrogen gas to afford a metal carbene intermediate.
