An iron-catalyzed diboration reaction of alkynes with bis(pinacolato)diboron (B2pin2) and external borating agents (MeOB(OR)2) affords diverse symmetrical or unsymmetrical cis-1,2-diborylalkenes. The simple protocol for the diboration reaction can be extended to the iron-catalyzed carboboration of alkynes with primary and, unprecedentedly, secondary alkyl halides, affording various tetrasubstit...

Following our ab initio nonlinear optical (NLO) materials design guidelines, in this Letter, we discovered a novel type of structure to realize potential deep-ultraviolet (DUV) NLO performance the classical beryllium borate system. By densely stacking NLO-active layered frameworks, key scheme for structural evolution from (Be2BO3F2) layers KBe2BO3F2 (KBBF) (Be2BO5H3) berborite is illustrated. B...

Large preservative-treated timbers and poles can develop internal external decay as they age in service. Arresting this damage pose a challenge, especially decay. Boron plays an important role helping arrest fungal attack variety of applications. This paper discusses the use borates component pastes for limiting boron solutions or rods arresting Long-term field trials show that movement is init...
