Spectacular platinum(0): 1,2‐Oxaplatinacycles 2 were formed unexpectedly from 2‐hydroxybenzyl sulfide derivatives 1 by bond cleavage mediated by platinum(0) (see scheme; nb=norbornene). The thermal reaction of 2 gave novel six‐membered 1,2,3‐oxaphosphaplatinacycles through ring expansion accompanied by the insertion of a phosphorus atom into the PtO bond and the 1,2‐shift of a phenyl group.
壮观铂(0):1,2- Oxaplatinacycles 2是从2-羟基苄基硫醚衍生物出人意料地形成1由铂(0)介导的键裂解(参见方案; NB =降冰片烯)。的热反应2得到通过扩环伴随磷原子到的Pt的插入新颖六元1,2,3- oxaphosphaplatinacycles O键和苯基的1,2-移位。
