phospha-Michael addition reaction of nitroalkenes to afford diversely substituted β-nitrodiazaphosphonates. This transformation takes place at room temperature under catalyst-free conditions and exhibits broad functionalgroup tolerance. The key to success in catalyst, additive-free reaction conditions is the suitable hydrogen-bond activation of the nitro group by a Brønsted acid (thiourea), which

salt of HL2 has been determined. The complex [Pd(L1)2] was fully characterized, but in contrast to other phosphinothiolates, complexes with the M(L)3 stoichiometry could not be prepared. Reaction of LH1 with Ni(II) led to cleavage of the arythiolate group and isolation of a thiolate bridged dimer, confirmed by an X-ray crystal structure. The Rh(I) complexes [Rh(nbd)L] (L = L1, L2) were characterized
