C-Alkylation of methanetetraboronic and methanetriboronic esters Matteson, Donald S.; Thomas, Joseph R. Journal of Organometallic Chemistry (), 24 (2), CODEN: JORCAI ; Cited by: Methanetetraboronic and methanetriboronic esters constitute a new type of one-carbon synthon which bears some analogy both to malonic ester and to Wittig reagents.

These reagents show promise of extending the utility of organoboron chemistry to classes of compounds that are not compatible with hydroboration reactions. by: Deborylative alkylation reactions with chiral 1,1,2-tris-(boronates) were performed in the group of Morken, and they found that five equivalents of NaO t Bu in toluene were efficient to form the new C-C bond from one of the geminal boryl moieties.

The syn diastereoisomer was the predominant product, obtained as 1,2-diol upon oxidative workup. Vol Issue 2 Pages CC37, C39, (September ).

traboronic (64) and methanetriboronic esters, 57–6 3 gem- diborylalkanes, 26, 29, 64 and deprotonation of trialkyl- bora 66 have been found useful in a variety of syn. Reduction of the bis(9-borafluorenyl)methane 1 with excess lithium furnishes the red dianion salt Li2[1].

The corresponding dark green monoanion radical Li[1] is accessible through the comproportionation reaction between 1 and Li2[1].
