© 2022 Wiley-VCH GmbH. Metalation of tBu2PH(BH3) (1H), iPr2PH(BH3) (2H), iPrPhPH(BH3) (3H), Ph2PH(BH3) (4H) or (Mes)2PH(BH3) (5H) with one equivalent of nBuLi in either diethyl ether or THF gave the corresponding phosphido-borane complexes, which were obtained as single crystals of the solvates [{tBu2P(BH3)}Li(OEt2)]∞ (1Li), [{iPr2P(BH3)}Li(THF)2]∞ (2Li), [{iPrPhP(BH3)}Li(OEt2)2]∞ (3Li), [{Ph2P(BH3)}Li(OEt2)2]∞ (4Li), and [{(Mes)2P(BH3)}Li(THF)2]2 (5Li) after crystallization from diethyl ether; the alternative adduct [{Ph2P(BH3)}Li(TMEDA)]∞ (4Li(TMEDA)) was isolated from the reaction of 4Li with TMEDA. Similar metalation reactions between 1H, 2H or 4H and PhCH2Na gave the complexes [{tBu2P(BH3)}Na(THF)]∞ (1Na) and [{iPr2P(BH3)}Na(THF)]∞ (2Na), and [{Ph2P(BH3)}Na(TMEDA)(THF)]∞ (4Na(TMEDA)). Compounds 1Li, 2Li, 3Li, 4Li and 4Li(TMEDA) crystallize as zig-zag polymers, while 5Li crystallizes as a centrosymmetric dimer; compounds 1Na and 2Na crystallize as ribbon polymers, although these differ significantly in structure, while 4Na(TMEDA) crystallizes as a zig-zag polymer.
