Welfare practices for anaesthesiology trainees in Europe: A descriptive cross-sectional survey study.

Background: Current regulations of anaesthesiology training programmes may affect gender equity, female representation and leadership.

Objective: To describe the work regulations of anaesthesiology training programs and working conditions during the early period of child-rearing in European countries.

Design: Cross-sectional survey.

Synthesis of a carborane-substituted bis(phosphanido) cobaltate(i), ligand substitution, and unusual P fragmentation.

Oxidative addition of the P-P single bond of an -carborane-derived 1,2-diphosphetane (1,2-C(PMes)BH) (Mes = 2,4,6-MeCH) to cobalt(-i) and nickel(0) sources affords the first heteroleptic complexes of a carborane-bridged bis(phosphanido) ligand. The complexes also incorporate labile ligands suitable for further functionalisation. Thus, the cobalt(i) complex [K([18]crown-6)][Co{1,2-(PMes)CBH}(cod)] (cod = 1,5-cyclooctadiene) bearing a labile cyclooctadiene ligand undergoes facile ligand exchange reactions with isonitriles and -butyl phosphaalkyne with retention of the bis(phosphanido) ligand.

Phosphorus Analogues of [Ni(bpy)]: Synthesis and Application in Carbon-Halogen Bond Activation.

The neutral, homoleptic pyridylphosphininenickel(0) complex [Ni(2-Py-4,6-Ph-PCH)] () has been obtained by reaction of the formal Ni(0) source [(IPr)Ni(HC═CHSiMe)] with 2 equiv of 2-(2'-pyridyl)-4,6-diphenylphosphinine (). Compound can be oxidized both electrochemically and through the use of ferrocenium salts, to afford the corresponding Ni(I) complexes []BF, [(THF)]PF, and [](BAr). The structures of these salts reveal an interesting dependence on the nature of the anion.

A Phosphinine-Derived 1-Phospha-7-Bora-Norbornadiene: Frustrated Lewis Pair Type Activation of Triple Bonds.

Salt metathesis of 1-methyl-2,4,6-triphenylphosphacyclohexadienyl lithium and chlorobis(pentafluorophenyl)borane affords a 1-phospha-7-bora-norbornadiene derivative 2. The C≡N triple bonds of nitriles insert into the P-B bond of 2 with concomitant C-B bond cleavage, whereas the C≡C bonds of phenylacetylenes react with 2 to form λ -phosphabarrelenes. Even though 2 must formally be regarded as a classical Lewis adduct, the C≡N and C≡C activation processes observed (and the mild conditions under which they occur) are reminiscent of the reactivity of frustrated Lewis pairs.
