✦ Synopsis

1 Concerted [1.2]-shifts occur very easily in carbonium ions, (11, X = Y = E or CR,, * -+, but not in radicals (1). l -l , or carbanious, (1). * --. This is readily explained2 by considering the 3-centre orbitals of the transition state. Uowever concerted [1,2]-shifts with retention of configuration in the migrating group do also occur readily in a number of other situations where X and Y are heteroatou possessing lone-pair electrons.
