supporting information, p. 810 - 813 (2016/02/09)
A highly enantioselective hydrosilylation of 1,2-dicarbonyl compounds was successfully realized for the first time utilizing the combination of tricyclohexylphosphine and chiral alkenylborane derived in situ from diyne as a frustrated Lewis pair catalyst. A variety of optically active α-hydroxy ketones and esters were obtained in 52-98% yields with 86-99% ee's.

Titled 1,2,5-thiadiazolometacyclophane 1 was prepared via thiacyclophane 5 which was obtained by the reaction of di(bromomethyl) 2 with sodium sulfide under phase-transfer-catalyzed conditions.Cyclophane 1 gave the corresponding pyrene derivatives by the oxidative transannular reaction in the reaction with brominating reagent.Reduction of 1 with lithium aluminum hydride followed by acetylation with acetic anhydride gave a 4:1 mixture of cis- and trans-diamide 11 and 12 with a trace amount of cyclophane-ring-cleaved product 13.On the other hand, 13 was obtained as a major product in the reduction with metal sodium and diisobutyl aluminum hydride.

Benzoins react readily with idotriethylsilane to produce, in many cases, mixtures of deoxybenzoins and tetraarylfurans.
