Reactions of Gallaphosphaketenes with Silylenes: Formation of Gallaphosphenes versus Silaphosphenes
Year: 2025
Type: article
Abstract: Heavy main group element compounds with heteronuclear double bonds are of interest due to their fascinating reactivity. Herein, the synthesis of silaphosphenes L1Ga(X)PSiL2 (X = Cl 2a, Me 2b, L1 = [N(Dipp)C(Me)]2CH, Dipp = 2,6‐iPr2C6H3; L2 = PhC(NtBu)2) and L1Ga(Cl)PSiL4 4 (L4 = [N(Dipp)C(Me)]2) is reported, which are obtained from reactions of gallaphosphaketenes L1Ga(X)PCO (X = Cl 1a, Me 1b) with silylenes L2SiCl and the N‐heterocyclic silylene L4Si, respectively. In contrast, gallaphosphene L1GaPSi(Cl)L3 3 (L3 = DippNC(CH3)CHC(CH2)NDipp) formed in the reaction of 1a with the β‐diketiminate‐substituted silylene L3Si. Silaphosphenes 2a and 4 and gallaphosphene 3 are promising reagents for reactions with nucleophiles and electrophiles as is exemplarily demonstrated with HCl, MeI, MeOTf, MeLi, BnOH, BnNC, and CO2, respectively.
