B-bromo- or B-iodo-9-borabicyclononane reacts readily with 1-alkynes.Such haloboration reactions proceed through the Markovnikov addition of the X-B moiety to CC bonds and cis fashion.The bromoboration reaction occours chemoselectively at terminal CC bonds but not at internal CC, terminal and internal C=C bonds.The protonolysis of haloboration products with acetic acid gives corresponding 2-bromo- or 2-iodo-1-alkenes in excellent yields.

The right mix! A 10:1 mixture of AlBr3 and AlMe3 promotes the Diels-Alder reaction of hindered dienophiles. For example, the Diels-Alder reaction of an acetyldiene with a tert-butyldimethylsilyl (TBS) enol ether gave mainly the exo c
