Although controlling both the position of the double bond and E:Z selectivity in alkene isomerization is difficult, 1 is a very efficient catalyst for selective mono-isomerization of a variety of multifunctional alkenes to afford >99.5% E-products. Many reactions are complete within 10 min at room temperature. Even sensitive enols and enamides susceptible to further reaction can be generated. Catalyst loadings in the 0.01-0.1 mol% range can be employed. E-to-Z isomerization of the product from diallyl ether was only -6 times as fast as its formation, showing the extremely high kinetic selectivity of 1.

Conditions have been found for an efficient regioselective β-hydrosilylation of allylbenzene, 2-allyl-1-trimethylsiloxybenzene, 4-allyl-1,2-(methylenedioxy)benzene, allylpentafluorobenzene, and 4-allyl-2-methoxy-1-trimethylsiloxybenzene with D4H in the presence of Karstedt's-catalyst or platinum black under mild conditions leading quantitatively to functionalized tetramethylcyclosiloxanes 3.
