{ALF} Forms polymers via hydrosilylation of alkadienes and and alkynes.

{ALF} In the presence of TMS chloride and either LiBr or NaI, aromatic aldehydes are reduced directly to benzyl halides: Tetrahedron Lett., 25, 1103 (1984).

{ALF} In the presence of a catalytic amount of titanium isopropoxide, secondary and tertiary phosphine oxides can be reduced to the corresponding phosphines in high yield, avoiding pyrophoric reagents: Synlett, 1545 (2007).

{ALF} Reducing agent:

{ALF} With a Pd(0) catalyst, acetylenes are reduced to olefins (mainly cis): Tetrahedron Lett., 30, 4675 (1989).
