Previous studies of the reactivity properties of the complexes [Fe2S2(SR)4]2~a nd [Fe4S4(SR)4]2" have demonstrated the occurrence of thiolate ligand substitution reactions with retention of Fe2S2 and Fe4S4 core structures. Described in this report are reactions which provide chemical and electrochemical interrelationships of 1-Fe, 2-Fe, and 4-Fe synthetic analogues of the active sites of iron-sulfur proteins. These reactions include (i[Fe4S4(SPh)4]3~by electrochemical reactions; and (iii) tetranuclear dianion-tetranuclear trianion chemical reduction, [Fe4S4(SR)4]2" -* [Fe4S4(SR)4]3". These transformations are correlated with prior synthetic and ligand-exchange processes to provide an overall reaction scheme starting with a simple iron(II) salt, progressing through intermediate 1-Fe and 2-Fe species and terminating in the 4-Fe complexes with cubane-type stereochemistry. Reaction iii was accomplished using sodium acenaphthylenide in hexamethylphosphoramide as reductant. The product trianion was obtained as oxygen-sensitive, crystalline Me4N+ or Et4N+ salts and is an analogue of the 4-Fe active sites of reduced ferredoxin proteins. With its isolation synthetic analogues of five of the seven known physiological proteins have been obtained in substance.

Emergence is a multi-dimensional notion; the meanings it has acquired span the mythopoetic to the scientific, especially as found in complex systems. Examples of emergence in Navaho and Egyptian imagery underscore its diverse cultural origins and applications as well as suggesting an underlying archetypal quality to the core concept. A brief overview of the use of this term in science starting in the 17th century helps to locate the roots of modern emergent views in the philosophy of Leibniz. Jung's own use of early systems approaches was a part of his formulations of a 'third' position associated with the transcendent function. As this paper was delivered at the 50th anniversary conference of the Journal of Analytical Psychology, aspects of the emergence of the Journal within the contents of the first issue are explored. Attention is drawn to several articles, especially a case of brief child therapy done by Robert Moody. His approach to working his case is strikingly modern and vividly demonstrates principles of emergence within the clinical setting. Following this there is a discussion of some neuroscientific research on neural body maps, pointing to the experience of feelings as an emergent process. It is suggested that feelings derive from phase transitions in the brain's body mapping states. A reconsideration of a seeming impasse in the case described by Moody leads instead to a view of the initial phase of treatment as a pre-critical period. Research findings on mirror neurons are presented in terms of the feeling of empathy. Subjective feelings are then shown to be associated with moments of emergence, especially surprise and curiosity, exemplified by a case from the author's practice.

In presenting clinical case material for a panel on archetypes and/or primal phantasies an initial discussion of archetypes as emergent phenomena organizing 'moments of complexity' is given(1) . The relationship of such moments to 'moments of meeting' as developed by the Boston Change Process Study Group is commented on and explored within the context of the case. A condensed report of a multi-year analytic treatment of a bipolar patient having a severe trauma history is offered for discussion. Several unusual, enigmatic events are detailed to illustrate the occurrence of moments of complexity. Dreams highlighting psychological transformation stemming from a changing relationship to emerging archetypal material related to a psychotic process in the patient are offered to further detailed moments of complexity.

Advances in the understanding and articulation of enactments allow a reassessment of analytical psychology's method of amplification. Subjective and objective aspects of the amplificatory process, evolving notions of its role in analysis together with the use of countertransference phenomena provide the frame for reexamination of this method. Using a single analytic day, this paper explores the inevitable play of enactments with a focus on countertransferential components contained in the act of amplification. An internal examination of such an act is used to attempt to identify and differentiate the operative personal, interpersonal and collective aspects. The impact and traces of this act are followed through the workings of the day and demonstrate that the impulse to amplify is a suitable object for analytic scrutiny. This leads to a more general question of the mythic nature of enactments.
