The electrophilic iron-carbene chelate complexes 1 and 2 react with alkoxides RO to give the neutral chelate complex 3 and the carbene complex 4, respectively. Depending on the nature of the chelating ortho substituent, selective activation of the Ar-Cl or Ar-C bond occurs; these processes are promoted by the chelation.

Up to 45% of patients with Parkinson's disease (PD) experience impulse control disorders (ICDs), characterized by a loss of voluntary control over impulses, drives or temptations. This study aimed to investigate whether previously identified genetic and psychiatric risk factors interact towards the development of ICDs in PD. A total of 278 de novo PD patients (ICD-free at enrollment) were selected from the Parkinson's Progression Markers Initiative database.

Background: Long-lasting insecticidal nets (LLINs) were once fully effective for the prevention of malaria; however, mosquitoes have developed resistance to pyrethroids, the main class of insecticides used on nets. Dual active ingredient LLINs (dual-AI LLINs) have been rolled out as an alternative to pyrethroid (PY)-only LLINs to counteract this. Understanding the minimum community usage at which these LLINs elicit an effect that also benefits non-users against malaria infection is important.
