TL;DR: In this article, the synthesis of 1,4-dimethyl-2,3,5,6-tetra-n -alkyl-1,4diboracyclohexa-2.5-dienes from the reaction of di-n-alkylacetylenes with the methylborylene-generating system 2C 8 K/MeBBr 2 is described.

TL;DR: In this paper, 1-Methylborepin (I) is judged to be aromatic on the basis of a) the value of its Huckel MO resonance energy, b) the ring-current effect on its 1H NMR spectrum, and c) its degree of aromaticity based on Julg's criterion.

TL;DR: The aromatic compounds 1-methylborepin (I) and 1methyl-3,6-dideuteroborepin(XXII) are formed in the reactions between methylboron dibromide and the products of the hydrostannation of a 1/1 cis/trans mixture of 1,5-hexadiyn-3-ene (XIV) with diethylbromotin hydride and diethymethylbrominitriou deuteride, respectively as discussed by the authors.

TL;DR: In this paper, the synthesis of alkyl-substituted 1,4-dimethyl-1, 4-diboracyclohexa-2,5-dienes from dialkylacetylenes and the system C8K/MeBBr2 is described.
