Bulky P,PO ligands were designed to inhibit isomerization and reduction side reactions during the crosscoupling between sterically hindered aryl halides and alkylboronic acids. Suzuki–Miyaura cross‐couplings between di‐ortho‐substituted aryl bromides and acyclic secondary alkylboronic acids have been achieved with high yields. The method has also enabled the preparation of ortho‐alkoxy di‐ortho‐substituted

Synthetic, biodegradable nanoparticles (NPs) encapsulating at least one of a signal 1 protein, a signal 2 protein, and/or a signal 3 protein are disclosed, which, when transfected into one or more a cancer cells, reprogram the one or more cancer cells into “tumor-derived APCs” in vivo to activate T-cells and natural killer (NK) cells for systemic tumor rejection. The NPs can be used for treating cancers, in particular metastatic cancers.
