Ethyl N-alkylcarbamates via hydroboration. The reaction of trialkylboranes with carboethoxynitrene is best conducted under phase-transfer conditions (equation I). Either benzyltriethylammonium chloride or methyl trioctylammonium chloride is a satisfactory catalyst.2... 

PTC = phase-transfer catalysis KOH/HjO/light petroleum (bp 50-70°C)/methyl-trioctylammonium chloride (Aliquat 336). 

The PVC membrane compositions consist of a neutral carrier and ion exchange ionophores as indicated in Table I. The K membrane includes valinomycin as the ionophore and is plasticized by 2-ethyl-hexyladipate (Fluka). The Na+ membrane contains methyl monensin and tris(2-ethylhexyl)phthalate. Tri-n-dodeclyamine is the ionophore for pH and tridodecylmethyammonium chloride is the ion exchanger for Cl. HC03 utilizes 4-butyltrifluorophenone for C03 detection as well as trioctylammonium chloride ion exchanger. Both anion membranes are plasticized with dioctyladipate.

Quaternary salts can be used in catalytic amount in liquid-sobd phase transfer conditions. For example, solid potassium acetate reacted with benzyl chloride in acetonitrile using A -methyl-MMA -trioctylammonium chloride (Aliquat 336) as the phase transfer catalyst (PTC) (Eq. 9.10) [38].
