The lecture will summarize the most recent achievements in the area of transition metal-mediated reactivity of elemental phosphorus deriving from the authors' own research at ICCOPM-CNR Florence. Highlights of the presentation will include:
• the metal-mediated activation of white phosphorus with particular emphasis to the unusual hydrolytic behavior of the P4 molecule following its η1-coordination to a metal centre (Fe, Ru, Os), which affords a variety of organometallic compounds stabilizing unusual low-valent phosphorus species as ligands;1
• the high pressure reactivity of red phosphorus with water and other small molecules;2
• some preliminary results dealing with the chemistry of the less reactive allotrope of the element, i.e. black phosphorus,3 including the easy access to 2D-flakes of phosphorene (the all-P counterpart of graphene) via a solution synthesis which avoids the use of the boring and scarcely productive scotch-tape exfoliation method and its reactivity with organometallic synthons.
