4062-60-6, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 4062-60-6, Name is N1,N2-Di-tert-butylethane-1,2-diamine,introducing its new discovery.
Synthesis and crystal structures of (Benzyl)triphenylphosphonium Bromides, [C6H5-CH2P(C6H5) 3]+Br- and [C6H5-CH2P(C6H5) 3]+Br3-
(Benzyl)triphenylphosphonium bromide, [C6H5-CH2P(C6H5) 3]+Br- (CH2Cl2) (1) has been prepared by the reaction of triphenylphosphine with benzylbromide and its structure determined. The colorless crystals are triclinic, space group P1, Z = 2, a = 976.0(3), b = 1069.0(3), c = 1226.1(4) pm. alpha = 94.13(3), beta = 104.70(3), gamma = 100.14(3). The lattice contains Br- anions and [C6H5-CH2P(C6H5) 3]+ cations. [C6H5-CH2P(C6H5) 33]Br3 (2) has been obtained by treating compound 1 with equimolar quantities of elemental bromine in methylene chloride solution. The red crystals of 2 are monoclinic, space group P21/c, Z = 4, a = 917.9(2), b = 1022.6(2), c = 2573.6(5) pm, beta = 99.11(2), and comprise[C6H5-CH2P(C6H 5)3]+ cations and linear, slightly asymmetrical Br3- anions with bromine-bromine distances of 246.19(11) and 263.69(11) pm.
