Triphospha[3]ferrocenophane Fe(CH-PTip)PCl (Tip = 2,4,6-tri(isopropyl)phenyl) has been prepared and its suitability to generate the corresponding bisphosphanylphosphenium ion has been explored. By formal addition of P to the latter, an unprecedented tetraphosphenium ion forms which likewise is capable of P transfer and qualifies as Lewis superacid based on its computed fluoride ion affinity. As a solid, this species is stable and conveniently storable, featuring a remarkably long P-P bond (2.

- The crystalline cyclic (alkyl)(amino)carbene fc(CPh-C-NMes) is highly reactive and unstable in solution due to its ability to insert into C-H bonds, a process that doesn't occur in the related compound fc(CPh-C-N-p-CH-tBu).
- Although fc(CPh-C-N-p-CH-tBu) (1) cannot undergo the same insertion, it is too short-lived to isolate because it quickly rearranges to form a distinct cyclic enamine through an unusual decomposition process.
- Trapping experiments with various reagents have led to the formation of stable compounds, indicating that 1 is an even stronger ambiphile than A, and both compounds do not react with
Unicellular eukaryotic plankton communities (protists) are the major basis of the marine food web. The spring bloom is especially important, because of its high biomass. However, it is poorly described how the protist community composition in Arctic surface waters develops from winter to spring.
