Safe- and convenient-to-handle surrogates of hazardous chemicals are always in demand. Recently introduced cyclohexa-1,4-dienes with adequate substitution fulfil this role as El+/H- equivalents in B(C6F5)3-catalysed transfer reactions of El-H to π- and σ-donors (C 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 000000000000000000000000000...

Whilst the primary goal of the project is develop an anthropomorphic system with the ...
