Synthetic example 6
[0077] Synthesis Example 6: Synthesis of Donor A27
[0078]
[0079]Under nitrogen protection, add A27-1 (2mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolane-2- Base)-tetraphenylsilane (2mmol), use 1:3 ethanol / toluene (100ml) as solvent, add 9% potassium carbonate aqueous solution (9ml), and tetrakistriphenylphosphine palladium (46mg, 0.04mmol) as catalyst , heated to reflux for 12 hours, cooled and then filtered to rinse the filter cake with ethanol to obtain the intermediate product of chemical formula A27-2, which was directly used in the next reaction.
[0080]
[0081] Put A27-2 into a 250mL round bottom flask under nitrogen protection, add 4-tetraphenylmethane borate (2mmol), use 1:3 ethanol / toluene (100ml) as solvent, add 9% potassium carbonate aqueous solution (9ml ), and tetrakistriphenylphosphine palladium (46mg, 0.04mmol) as a catalyst, heated to reflux for 12 hours, filtered after cooling and rinsed the filter cake with ethanol to obtain the final product che...
Synthetic example 9
[0088] Synthesis Example 9: Synthesis of Donor B53
[0089]
[0090] This example is basically the same as Synthesis Example 7, except that in this example, B45-1 needs to be replaced with B53-1 of 1 / 2 the amount of substance (mol), and 3-bromo-9,9 The '-spirobifluorene was replaced by an equivalent amount (mol) of 4-bromotetraphenylsilane. The final product B53 (0.76g, yield 69%, HPLC analysis purity 99.72%). MALDI-TOF-MS results: Molecular ion peak: 1129.42 Elemental analysis results: Theoretical value: C: 86.05%; H: 5.26%; N: 3.72%; Si: 4.97%; Experimental value: C: 86.01%; H: 5.23 %; N: 3.77%; Si: 4.99%.
Synthetic example 10
[0091] Synthesis Example 10: Synthesis of Donor B67
[0092]
[0093] Under nitrogen protection, add B67-1 (2mmol), 3-chloro-9,9-diphenylfluorene (2mmol) into a 250mL round bottom flask, use 1:3 ethanol / toluene (100ml) as solvent, add 9% potassium carbonate aqueous solution (9ml), and tetrakistriphenylphosphine palladium (46mg, 0.04mmol) were used as a catalyst, heated to reflux for 12 hours, filtered after cooling and rinsed the filter cake with ethanol to obtain the intermediate product B67-2, which was directly used in the following step response.
[0094]
[0095] Under nitrogen protection, B67-2 (2mmol), 3-chlorospiro[fluorene-9,9-oxanthene] (2mmol) was added to a 250mL round bottom flask, and 1:3 ethanol / toluene (100ml) As a solvent, add 9% potassium carbonate aqueous solution (9ml), and tetrakistriphenylphosphine palladium (46mg, 0.04mmol) as a catalyst, heat and reflux for 12 hours, filter after cooling and rinse the filter cake with ethanol to obtain the final ...
