Hydroboration of 1,3-butadiene, isoprene, myrcene, 2,3-dimethyl-1,3-butadiene, and 1,3-cyclohexadiene with catecholborane(1,3,2-benzodioxaborole) in the presence of Pd(PPh3)4 or Rh4(CO)12 catalysts proceeds smoothly to provide 2--1,3,2-benzodioxaboroles in very high regio- and stereoselectivity.

The first practical hydrozincation of butadiene and 2-alkylbutadienes has been achieved by a combination reagent including ZnI2, LiH, and Cp2TiCl2 in a ratio of 1:2.2:0.1 to yield the corresponding allylzinc reagents in THF, which, in turn, react with a variety of carbonyl compounds.
