Abstract
In one aspect, phosphine compounds comprising three adamantyl moieties (PAd3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.
Claims9
A method of synthesizing a tri-(adamantyl)phosphine compound, PAd3, comprising:
- providing a reaction mixture including di-(adamantyl)phosphine (PAd2) and a substituted adamantyl moiety of the formula R—X, and reacting the PAd2 and substituted adamantyl moiety via an SN1 pathway to provide the PAd3, wherein R is an adamantyl moiety selected from the group consisting of adamantyl, diamantyl, and triamantyl, and X is a leaving group operable for dissociation into an anion under the SN1 pathway.
