Catalyst-free autocatalyzedN-alkylation of heteroarylamines with alcohols is achieved by tautomerization-induced ready generation of carbonyl intermediates from alcoholsviaTM-free MPV–O reaction.

Data on the heterophase polymerisation of styrene under conditions of surfactant formation at the monomer–water interface are generalised. A new, in principle, approach is proposed the essence of which is to obtain a monomer emulsion simultaneously with the synthesis of an emulsifier at the monomer–water interface and with initiation of the polymerisation in the interfacial layer. The preparation of
