(Sia)2 BH THF/ H2O2, OH- w/a terminal alkyne this makes an aldehyde

can this happen with an internal alkyne?

Yezzur, you'd get a ketone with internal alkynes. However know this: internal alkynes always give 2 products.

Actually I don't think it's (Sia)2 BH THF/ H2O2, OH- that does it. Don't take my word for it, but I think BH3/H2O2 OH- will give you a ketone with an internal alkyne not (Sia)2 BH THF/ H2O2, OH-.
