The synthesis and characterisation of novel o-substituted benzyldi-t-butylphosphine–boranes

The novel compounds o-(chloromethyl)benzyldi-t-butylphosphine–borane and o-(methoxymethyl)benzyldi-t-butylphosphine–borane have been synthesised in 54% and 51% yields, respectively, and have been fully characterised. An improved method for the synthesis of α-chloro-α′-methoxy-o-xylene is also reported.
