, p. 805 - 808 (2003)
No base is necessary: Excellent yields are produced on addition of organoboronic acids to alkynes under mild reaction conditions when palladium compounds are used as catalysts (see scheme). Unlike the Suzuki-type cross-coupling reaction, the current reaction occurs in an acidic medium.
Gold-catalyzed isomerization of unactivated allenes into 1,3-dienes under ambient conditions

We have developed a gold-catalyzed isomerization of unactivated allenes into 1,3-dienes with nitrosobenzene as an additive. This reaction proceeded almost exclusively at room temperature for highly substituted allenes. The utility of this reaction is manifested by the development of one-pot [4+2]-cycloaddition of allenes and reactive alkenes.
REGIOSELECTIVE ALKYLATION OF 3-SUBSTITUTED 3-SULFOLENES

Remarkable directing effect of the substituent on the double bond of 3-sulfolene was found in the reaction with alkyl iodides under basic conditions; electron donating groups effect selective substitution at the 2-position while electron withdrawing group
