Abstract

Results Haloalkaneboronic Esters.-In previous work, 6 dibutyl vinylboronate (1) was found to be inert to liquid hydrogen bromide at-70". We have now found that in refluxing hydrogen iodide a mixture of dibutyl 1-iodoethaneboronate (2) and 2-iodoethaneboronate (3) is formed in about 60% yield. The proportion of 1 isomer 2 was found to be 62% by nmr, based on the
