Diborane reaction with

Reduction. Coumarin is reduced to o-hydroxycinnamyl alcohol by reaction with lithium aluminum hydride (21). By reaction with diborane coumarin gives o-aUylphenol [1745-81 -9] (22). [Pg.320]

Hydroboration affords an efficient preparation of the 5a-A -system (141, for example) from A" -3-ketones. Reaction with diborane followed by decomposition of the organoboron intermediate with refluxing acetic anhydride gives good yields of olefins. Ketones must be protected, and alcohols are transformed to acetates. A -7-Ketones yield 5oc-A -olefins (for example, 138). [Pg.347]

Cluster expansion reactions with diborane provide an alternative route to intermediate closo-carboranes, e.g. ... [Pg.183]

Obviously, the basic site in KB5H8 is its basal B-B single bond and, therefore, reactions with Lewis acids are to be expected. A typical example is the reaction with diborane in ether at —78 °C which generates via its //-adduct (3c2e-BBB bond) the nido-undeca-hexaborate(l—), B6Hn, by cluster expansion. This anion can be proto nated to B Hn [53],... [Pg.61]

A distinction between silanol groups and adsorbed free water was attempted by Shapiro and Weiss (200a) and Weiss et al. (200b) using the reaction with diborane. Diborane reacts with free water with evolution of six moles of hydrogen per mole of consumed reagent ... [Pg.231]
