Reactions of Arylcarbenes with Lewis Acids
No full textThe reactions of the three triplet ground state arylcarbenes diphenylcarbene 1, fluorenylidene 2, and dibenzocycloheptadienylidene 3 with the Lewis acids H2O, ICF3, and BF3 were studied under the conditions of matrix isolation. H2O was selected as typical hydrogen bond donor, ICF3 as halogen bond donor, and BF3 as strong Lewis acid. H2O forms hydrogen-bonded complexes of the singlet carbenes with 1 and 2, but not with 3. This is rationalized by the larger singlet-triplet gap of 3, which does not allow to stabilize the singlet state below the triplet state by hydrogen bonding. With ICF3, both 1 and 3 form halogen-bonded complexes of the singlet states of the carbenes. This indicates that halogen bonding stabilizes singlet carbenes more than hydrogen bonding. Carbene 2 reacts differently from 1 and 3 by forming an iodonium ylide, thus avoiding antiaromatic destabilization of the fluorenyl unit. With BF3, all three carbenes form zwitterionic Lewis acid/base complexes

Appreciative of Hook's favorable comments; the necessity and rarity of an artist's finding congenial appreciators; art as a universal language (V.S. poetry); purpose of art; would like to correspond with Hook (has Sands told Hook he suggested this?)

Neural correlates of processing valence and arousal in affective words
No full textPsychological frameworks conceptualize emotion along 2 dimensions, "valence" and "arousal." Arousal invokes a single axis of intensity increasing from neutral to maximally arousing. Valence can be described variously as a bipolar continuum, as independent positive and negative dimensions, or as hedonic value (distance from neutral). In this study, we used functional magnetic resonance imaging to characterize neural activity correlating with arousal and with distinct models of valence during presentation of affective word stimuli. Our results extend observations in the chemosensory domain suggesting a double dissociation in which subregions of orbitofrontal cortex process valence, whereas amygdala preferentially processes arousal. In addition, our data support the physiological validity of descriptions of valence along independent axes or as absolute distance from neutral but fail to support the validity of descriptions of valence along a bipolar continuum
