I.—The preparation of ethyl bromide

Preparation of ethyl magnesium bromide for regiospecific analysis of triacylglycerols.

This paper presents a procedure for preparation of a Grignard reagent, ethyl magnesium bromide, used for partial deacylation of triacylglycerols (TAG) in their regiospecific analysis. Magnesium turnings were reacted with ethereal solution of bromoethane in a screw-capped test tube to synthesize 2 mL of 1 M ethyl magnesium bromide. Continuously stirred with a vortex mixer, the reaction smoothly ...

2-(2,4,6-Trichloro­phen­oxy)ethyl bromide

In the title compound, C(8)H(6)BrCl(3)O, there is a weak intra-molecular C-H⋯Cl hydrogen bond involving the O bound methylene group. Intermolecular Cl⋯Cl contacts [3.482 (2) Å] are present in the crystal structure.

Addition of Ethyl Alcohol to Triethyl Propargyl Ammonium Bromide

Rearrangement of propargyl amine salt, in the presence of a base was studied and it was concluded that this occurs through an allenic intermediate.

IThe theory of optimal reductions

We introduce a new class of higher order rewriting systems, called Interaction Systems (IS's). IS's come from Lafont's (Intuitionistic) Interaction Nets Lafont 1990] by dropping the linearity constraint. In particular, we borrow from Interaction Nets the syntactical bipartitions of operators into constructors and destructors and the principle of binary interaction. As a consequence, IS's are a ...
