Tri-n-butylphosphine is used as a catalyst modifier in the cobalt-catalyzed hydroformylation of alkenes for industrial use. It is also used as a strong reducing agent and polymerization cross-linking catalyst. It is a used as an intermediate for phase transfer catalysts.

A useful alternative to Triphenylphosphine, L02502 in many applications. Advantages include its greater reactivity and the water-solubility of the by-product phosphine oxide, simplifying its removal.
In combination with phenyl isocyanate and a Pd catalyst, converts cinnamyl alcohol directly to a phosphorane, which reacts with aldehydes to give conjugated dienes: Chem. Lett., 1449 (1988):
Can behave as a hypernucleophilic catalyst in acylation reactions, with similar results to 4-(Dimethylamino)pyridine, A13016: J. Am. Chem. Soc., 115, 3358 (1993).
Effective catalyst for the Baylis-Hillman reaction with less tendency than the usual DABCO (1,4-Diazabicyclo[2.2.2]octane, A14003) to promote aldol type side reactions: J. Org. Chem., 62, 1521 (1997).
For example of its use in Mitsunobu-type reactions, see Diisopropyl azodicarboxylate, L10386.
