“…Pombeiro and co-workers reported the nucleophilic addition of a series of ketoximes R 1 R 2 CNOH ( 74 ) to the nitrile ligands in the platinum(II) complexes trans -[PtCl 2 (NCR 3 ) 2 ] ( 75 ). − This addition proceeded in CH 2 Cl 2 under reflux for 15–60 min (Scheme ) and led to the mono- and bis-addition trans -[PtCl 2 (NCR 3 ){H N C(R 3 )ONCR 1 R 2 }] products ( 76 ; 40–62%; a) and trans -[PtCl 2 {H N C(R 3 )ONCR 1 R 2 } 2 ] ( 77 ; 45–52%; b and c), respectively, featuring monodentate coordinated O -iminoacylated oximes. These reactions were reported to give a 1:1 mixture of trans - and cis -isomers of the bis-addition products [PtCl 2 {H N C(R 3 )ONCR 1 R 2 } 2 ], but this statement requires additional confirmation, as cis/trans -isomerization has never been observed under similar conditions in similar systems. ,− The unstable imine HNC(CH 2 CO 2 Me)ONCMe 2 was liberated from 77 (R 1 /R 2 = Me/Me) by treatment of the complex with 2 equiv of dppe in CDCl 3 …”

This review classifies and summarizes the past 10-15 years of advancements in the field of metal-involving (i.e., metal-mediated and metal-catalyzed) reactions of oximes. These reactions are diverse in nature and have been employed for syntheses of oxime-based metal complexes and cage-compounds, oxime functionalizations, and the preparation of new classes of organic species, in particular, a wide variety of heterocyclic systems spanning small 3-membered ring systems to macroheterocycles. This consideration gives a general outlook of reaction routes, mechanisms, and driving forces and underlines the potential of metal-involving conversions of oxime species for application in various fields of chemistry and draws attention to the emerging putative targets.
